Biochemistry: timeline of key events

A chemist and physiologist, Hoppe-Seyler helped pioneer the disciplines of biochemistry and molecular biology. He studied fluids of the body such as blood, haemoglobin, pus, bile, milk, and urine and was the first to crystallise haemoglobin and observe its absorption spectrum. In addition he performed several important studies on chlorophyll and isolated several different proteins. Hoppe-Seyler lost both of his parents by the time he was nine years old and spent some of his childhood in an orphan asylum in Halle. He was subsequently adopted by Georg Seyler, the husband of his older sister.1825-12-26T00:00:00+0000Kuhne was a physiologist who coined the term 'enzyme' after his discovery of the protein-digesting enzyme trypsin in 1876. Early on in his career Kuhne worked on the physiology of muscle. In later years he turned to looking at the chemistry of digestion. Kuhne is also known for having helped to elucidate the chemical changes that occur in the retina under the influence of light. 1837-03-28T00:00:00+0000Fischer was a German chemist who opened up the era of biochemistry by clarifying the structure of sugars and enzymes and elaborating how they were formed. In 1902 he was awarded the Nobel Prize for Chemistry for demonstrating the structure of biological compounds, including sugars proteins and purines. He synthesised many natural occurring molecules for the first time, including glucose, caffeine, and uric acid. In addition, he managed to synthesis several amino acids and created small chains of them as precursors to protein formation. Fisher is also associated with the idea of the 'lock and key' mechanism which is used to explain how enzymes catalyse certain reactions and not others.1852-10-09T00:00:00+0000Takamine was the first to isolate and purify the hormone adrenalin from animal glands. It was the first effective bronchodilator for asthma. This he achieved in 1901 while working for the division of chemistry at the Department of Agriculture and Commerce in Japan. It was the first pure hormone isolated from a natural source.1854-11-03T00:00:00+0000Buchner was a chemist and zymologist. In 1907 he was awarded the Nobel Prize for Chemistry for his discovery of cell-free fermentation. This was based on some experiments he carried out in 1897, during which he found that yeast extract could form alcohol from a sugar solution without any living cells. He discovered that the fermentation was driven by an enzyme, zymase, inside the yeast cells. It provided the first evidence that biochemical processes were driven by enzymes formed inside cells. He was killed in the First World War while serving as a general. 1860-05-20T00:00:00+0000Hopkins was a biochemist who shared the 1929 Nobel Prize for Physiology or Medicine for discovering vitamins and demonstrating they are an important nutrient in the diet. This was based on experiments he carried out on rats in 1901. He also helped establish the chemistry of muscle contraction, showing that lactic acid accumulates in working muscle in 1907. In 1922 he isolated and demonstrated the importance of tripeptide gluathione to the utilisation of oxygen by the cell. 1861-06-20T00:00:00+0000Harden was one of the key founders of British biochemistry. He won the 1929 Nobel Prize for Chemistry for working out the importance of two enzymes and phosphoric acid during the fermentation process. These he discovered while investigating the fermentation of sugars by bacteria, a project undertaken between 1900 and 1914 that was designed to find a way of differentiating between different groups of Escherichia coli. The work involved grinding bacteria and extracting the intracellular juices.1865-10-12T00:00:00+0000Tsvet was a botanist who is credited with the invention of adsorption chromatography. He first described the method in 1901. His technique involved using ether and alcohol to extract plant pigments from leaves and then passing the resulting solution through a column of calcium carbonate. The advantage of the process was that it separated pigments into different coloured bands. By using the process Tsvet was able to demonstrate that plants had two forms of chlorophyll and eight additional pigments. Chromatography is now an important laboratory technique for the separation of a mixture.1872-05-14T00:00:00+0000Euler-Chelpin was a Geman-born Swedish biochemist who shared the Nobel Prize in 1929 for working out the role of enzymes in the fermentation of sugar. His work laid the foundation for understanding the important processes that take place in the muscles for supplying energy. He also helped show that colouring agents like betacaronoids in vegetables get transformed into vitamin A in the body. 1873-02-15T00:00:00+0000Windaus was a German steroid chemist who helped discover 7-dehydrocholesterol, the chemical precursor of vitamin D in 1926. He showed that exposure to sunlight converted the molecule into vitamin D. His finding explained why sunlight was important to preventing rickets, a bone disease that afflicts humans who have a vitamin D deficiency. In 1928 Windaus was awarded the Nobel Prize in Chemistry for his work on sterols and their relation to vitamins. He also helped work out the chemical steps involved in the transformation of cholesterol to vitamin D31876-12-25T00:00:00+0000Fleming was a biologist and microbiologist. He first made his mark through his discovery of lysosyme in 1923. This is an enzyme produced in the tears, saliva, mucus and human milk which is an important part of the immune system. Today he is best known for having found penicillin, a mould subsequently developed as the first antibiotic drug to treat bacterial diseases. He was awarded the Nobel Prize in 1945 for this discovery.1881-08-06T00:00:00+0000Svedberg was a nuclear scientist who in 1923 invented the analytical ultracentrifuge, a high speed centrifuge that makes it possible to spin large molecules at forces in excess of a million times the force of gravity. This provided a means to separate large macromolecules such as proteins out of a solution. Svedberg used his ultracentrifuge to work out the relative molecular masses of large molecules in high polymers and proteins. He managed to determine the molecular weight of haemoglobin in blood and casein in milk. Svedberg was awarded the Nobel Prize in 1926 for his invention of the analytical ultracentrifuge. which he used to research colloids and proteins.1884-08-30T00:00:00+0000Kendall made several contributions to biochemistry and medicine. He is best known for isolating the steroid cortisone from the adrenal gland cortex, subsequently used to treat rheumatoid arthritis, for which he shared the Nobel Prize for Medicine in 1950. He also isolated thyroxine, the main hormone secreted by the thyroid gland which is vital to digestion, heart and muscle function and brain development and bone maintenance. 1886-03-08T00:00:00+0000Rose was a biochemist and nutritionist. He isolated the amino acid threonine in 1932 and demonstrated in rats that a diet that lacked the amino acid stunted their growth. By 1949 he had established that ten amino acids were vital to human health: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Based on this work he was appointed to the US Food and Nutrition Board of the National Research Council which drew up dietary recommendations. 1887-04-04T00:00:00+0000Sumner was a biochemist who showed that enzymes are proteins and can be crystalised for which he shared the Nobel Prize in Chemistry in 1946. He crystalised his first enzyme, urease, in 1926. This he achieved by mixing purified urease with acetone and then chilling it. Using chemical tests he showed the enzyme was a protein. His work provided the first proof that enzymes were proteins1887-11-19T00:00:00+0000Harger was a biochemist and toxicologist who invented the the first practical test for measuring alcohol levels in drivers. He developed this in 1931. Known as the Drunkometer, the test collected a sample of a driver's breath directly into a balloon. This was then pumped into an acidifed potassium permanganate solution. If any alcohol was present in the sample the solution changed colour. Harger's test greatly helped reduce the number of road deaths from drunk driving. 1890-01-14T00:00:00+0000Northrop shared the 1946 Nobel Prize for Chemistry for helping to develop the technique for purifying and crystallising enzymes and virus proteins. His work showed that enzymes obey the laws of chemical reactions and that they are proteins. In 1930 he crystallised pepsin, an enzyme present in gastric juice necessary for digestion. Eight years later he isolated the first bacterial virus (bacteriophage). This he proved to be a nucleoprotein. Other enzymes that he managed to isolate and crystalise were trypsin and chymotrypsin, both important to the digestive process.1891-07-05T00:00:00+0000Banting was a physician who helped discover and isolate insulin. He also pioneered the extraction of insulin from pigs and cattle and demonstrated its use to treat diabetes in dogs. In 1923 he was jointly awarded the Nobel Prize in Physiology or Medicine for this work. 1891-11-14T00:00:00+0000Moore was a zoologist who devoted his career to studying the reoproductive tract of male mammals and the physiology of spermatozoa. He played a pivotal role in 1929 in isolating the testicular secretion containing the male sex hormones andresterone and testosterone. This discovery opened up the path to researching the chemical composition of the hormones and their production. 1892-12-05T00:00:00+0000Cohn developed a fractionation technique to separate blood into its components, paving the way to safer blood transfusion. During World War II he worked out methods for isolating serum albumin from blood plasma which is crucial to maintaining osmotic pressure in blood vessels and preventing their collapse. Thousands of soldiers were successfully treated on the battlefield with transfusions of purified albumin. Cohn subsequently developed mechanisms so that every component of blood could be used in transfusions.1892-12-17T00:00:00+0000Albert Szent-Gyorgyi was a biochemist who received the Nobel Prize in Physiology or Medicine in 1937 for isolating vitamin C and determining the components and reactions of the citric acid cycle. He subsequently worked on the biophysics of muscle movement and discovered that biochemical nature of muscular contraction. His findings revolutionised the field of muscle research. Later on he explored the connections between free radicals and cancer. 1893-09-16T00:00:00+0000Doisy was a biochemist who helped isolate two forms of vitamin K and determine their chemical structure in 1936-39, for which he received the Nobel Prize in Physiology or Medicine in 1943. The fact that Vitamin K helps promote blood-clotting means it is used widely in surgery and medicine. Doisy also helped isolate the sex hormones estrone (1929), estriol (1935), and estradiol (1935).1893-11-13T00:00:00+0000A German chemist and physiologist, Hoppe-Seyler helped pioneer the disciplines of biochemistry and molecular biology. He studied fluids of the body such as blood, haemoglobin, pus, bile, milk, and urine and was the first to crystallise haemoglobin and observe its absorption spectrum. In addition he performed several important studies on chlorophyll and isolated several different proteins. Hoppe-Seyler lost both of his parents by the time he was nine years old and spent some of his childhood in an orphan asylum in Halle. He was subsequently adopted by Georg Seyler, the husband of his older sister. 1895-08-10T00:00:00+0000Hench was a physician who helped discover cortisone, a hormone of the adrenal cortex, and demonstrate its utility for treating rheumatoid arthritis. He headed up the Department of Rheumatic Diseases at the the Mayo Clinic. Early on he hypothesised that steroids could alleviate the pain associated with the disease, but the difficulty and expense of production hindered his ability to try out his theory. The clinical trials were finally carried out in 1948 and 1949. Hench was jointly awarded the Nobel Prize for Medicine for his work in 1950.1896-02-28T00:00:00+0000Gerty Cori, nee Radnitz, was the third woman to win the Nobel Prize for Medicine and the first woman in America to do so. She shared the prize in 1947 with her husband Cari Cori, for discovering how the body metabolises glycogen, which is important to how the body stores energy. Born into a Jewish family, Cori studied medicine at the Karl-Ferdinands-Universität in Prague, an unusual path for a woman at the time. Throughout her career Cori experienced difficulties because she was a woman. In 1921 she was threatened with dismissal by the director of Roswell Park Cancer Institute if she continued her collaborative research with her husband. Later she struggled to get appointed full-professor at Washington University St Louuis, a position she gained only months before she won the Nobel Prize. 1896-08-15T00:00:00+0000Cori was a biochemist and pharmacologist who together with his wife Gerty Cori helped discover how the body metabolises glycogen, which is important to how the body stores energy. The two of them managed to isolate and purify glycogen phosphorylase, with which the achieved the test-tube synthesis of glycogen in 1943. They hypothesised that liver glycogen converts to blood glucose and reconverted to glycogen in the muscle, where it is broken down into lactic acid which provides the energy used in muscle contraction. Their work earned them the 1947 the Nobel Prize for Medicine together with Bernando Hossay. 1896-12-05T00:00:00+0000Hinshelwood was a physical chemist who shared the Nobel Prize for Chemistry in 1956 for helping to work out chemical reaction rates and reaction mechanisms. He subsequently did a lot of work on how environmental conditions affected the growth of bacterial cells. His findings on the relationship between the environment and chemical changes inside bacteria cells provided an important pathway to understanding the mechanisms behind bacterial resistance to antibiotics. 1897-06-19T00:00:00+0000The child of Polish-Jewish parents, Reichstein was a chemist who in 1933 managed to synthesise vitamin C. His name is associated now with the industrial process for the artificial synthesis of vitamin C. In 1950 he shared the Nobel Prize for Medicine for helping to isolate and explain the function of the hormones of the adrenal cortex and its therapeutic value for treating rheumatoid arthritis. He spent the last three decades of his life working on the phytochemistry and cytology of ferns. 1897-07-20T00:00:00+0000Kuhne was a German physiologist who coined the term 'enzyme' after his discovery of the protein-digesting enzyme trypsin in 1876. Early on in his career Kuhne worked on the physiology of muscle. In later years he turned to looking at the chemistry of digestion. Kuhne is also known for having helped to elucidate the chemical changes that occur in the retina under the influence of light. 1900-06-10T00:00:00+0000Kuhn was a biochemist who won 1938 Nobel Prize for Chemistry for his work on carostenoids, a group of nonnitrogenous yellow, orange and red pigments found in nature. One of these he found to be necessary for the fertilisation of certain algae. He was also awarded the Prize based on his work to determine the constitution of vitamin B2 which he also isolated. He later also helped isolate vitamin B6. Initially Kuhn turned down the Nobel Prize because he was forbidden to accept it by the Nazis with whom he collaborated in the denouncement of three of his Jewish colleagues. He finally accepted the Prize after World War II. Kuhn is also credited with the discovery of Soman, a deadly nerve agent, in 1944. 1900-12-03T00:00:00+0000du Vigneaud was a biochemist whose research focused on sulfur, proteins and peptides. In late 1940s he helped isolate and synthesise two pituitary hormones: vasopressin and oxytocin. Vasopressin is an antidiurtic hormone that helps protect cells from sudden increases or decreases in water which can affect the cell's function. Oxytocin is a neurohormone that helps contract the uterus during labour and stimulate the secretion of milk during lactation. He was awarded the Nobel Prize for Chemistry in 1955 for this work. Prior to this, in the 1930s, he helped identify the chemical structure of insulin and worked out the structure of biotin, a sulfur-bearing vitamin. 1901-05-18T00:00:00+0000A Swedish biochemist, Tiselius devised electrophoresis, a technique used to separate charged macromolecules like DNA, RNA and proteins according to their size. Electrophoresis is a chromatography technique that uses an electric field to separate a mixture of charged molecules. Tiselius also pioneered synthetic blood plasma. He was awarded a Nobel Prize in 1948 on the back of this work. 1902-08-10T00:00:00+0000Theorell trained in medicine and dedicated his career to understanding enzymes. He won the 1955 Nobel Prize for Medicine for 'discoveries concerning the nature and mode of action of oxidation enzymes.' He made the breakthrough in 1935. He was able to show that a yellow-coloured enzyme had two parts, both of which were essential to its function. Kossel's work laid the foundation for advances in understanding ADH enzymes which break down alcohol in the kidney. 1903-07-06T00:00:00+0000Gwei-djen was a biochemist who undertook pioneering work on metabolic pathways. In 1933, Gwei-djen took the bold decision to leave China, then isolated from the West, to study for a doctorate at Cambridge University where she remained for the rest of her career. By 1939 she had developed the first sensitive assay for detecting low levels of pyruvic acid, an intermediate involved in the breakdown of carbohydrates. Her work demonstrated that the levels of pyruvic acid could be raised by vitamin B1 deficiency and exercise. Gwei-djen worked closely with both Dorothy and Joseph Needham. Together with Joseph she compiled a series of book detailing Chinese achievements in science and technology. .1904-07-22T00:00:00+0000Stanley was a biochemist and virologist. In 1935 he managed to crystalise the tobacco virus, the causative agent of plant disease. This was a major breakthrough because prior to this no scientists had succeeded in finding out what viruses were. His work laid the foundation for other scientists, using x-ray diffraction, to work out the precise molecular structures and reproduction process of several viruses. During World War II he managed to purify several of the most common influenza viruses and developed a vaccine that was partly effective. In 1946 he shared the Nobel Prize for Chemistry for the 'preparation of enzymes and virus proteins in a pure form.'1904-08-16T00:00:00+0000Folkers was a biochemist who is best known for his role in the isolation of vitamin B12, which was inspired by the discovery it could help in the treatment of pernicious anaemia. This he did in the late 1940s while working in the research laboratories of Merck and Co. Folkers and his team at Merck went on to discover mevalonic acid, which plays a key role in the production of numerous important biochemical compounds, including carotenoids, steroids, and terpenes. They also isolated the two antibiotics: cathomycin and cyclorserine. 1906-09-01T00:00:00+0000Leloir was an Argentinian physician and biochemist who won the 1970 Nobel Prize for Chemistry for identifying nucleotides that are fundamental to the metabolism of carbohydrates. He made the discovery in 1948 while working with colleagues at the Instituto de Investigaciones Bioquímicas de la Fundación Campomar. While strapped for resources and equipment, Leloir and his team managed to determine the chemical origins of sugar synthesis in yeast and the oxidation of fatty acids in the liver. Leloir was the founder and director of the Instituto Campomar from 1947 to 1987. He was responsible for transforming the institute into an internationally renowned research hub for biochemistry. 1906-09-06T00:00:00+0000Levi-Montalcini is best known for sharing the Nobel Prize in 1986 for helping to discover and isolate the nerve growth factor which helps regulate the growth, maintenance, proliferation and survival of certian neurons. Banned by Mussolini from working in academia because she was Jewish, Levi-Montalcini conducted much of her early work in a makeshift laboratory in her bedroom. She later became the director of the Research Center of Neurobiology and the Laboratory of Cellular Biology in Washington University and founded the European Brain Research Institute. 1909-04-22T00:00:00+0000Dorothy Hodgkin, was a British chemist who pioneered protein crystallography, a technique the uses x-ray crystallography to determine the three dimensional structure of protein crystals. She used the technique to confirm the structure of penicillin, in 1945, for which she won the Nobel Prize in Chemistry in 1964. Hodgkin was the third woman to win the Nobel Prize. In addition to penicillin, Hodgkin published the first structure of a steroid and deciphered the structure of vitamin B12 and insulin. Her protein crystallography technique is now an essential tool for research into structural biology.1910-05-12T00:00:00+0000Lehmann was a biochemist who was renowned for his studies on the distribution of abnormal haemoglobins in many different human populations. This grew out of his interest in anaemia, begun when he served as assistant director of pathology to the North East India Command between 1942 and 1947. He helped to discover that a high incidence in the sickle-cell trait in several aboriginal southern Indian populations. Based on his work he hypothesised that the gene for the trait could have been brought to Africa from India during prehistoric migrations.1910-07-08T00:00:00+0000Lynen was a biochemist who was director of the Max Plank Institute for Cellular Chemistry. He helped determine the chemical mechanism for the production and regulation of cholesterol and fatty acid metabolism. In 1964 he was awarded the Nobel Prize for Medicine for this work. His findings opened the pathway to understanding the role of cholesterol in heart disease and stroke. 1911-04-06T00:00:00+0000A biochemist, Calvin shared the 1961 Nobel Prize for Chemistry for helping to demonstrate the chemical pathways of photosynthesis. Using the radioactive isotope carbon-14 as a tracer he was able to show the carbon movements through a plant during the photosynthesis process. He began his work on photosynthesis in 1946. Prior to this Calvin and his wife, Genevieve Jentegaard, investigated the chemical factors in the RH blood group system and managed to determine the structure of one of the Rh antigens. 1911-04-08T00:00:00+0000Stein was a biochemist who shared the 1972 Nobel Prize for contributing to understanding the composition and functioning of ribonuclease, an enzyme that catalyses the break down of RNA into smaller components. It was the first structure and sequence worked out for any enzyme. Stein carried out the work with his colleague Stanford Moore in 1963. The two scientists were aided by their invention of the first means for automated amino acid analysis. In addition to his work on ribonuclease, Stein showed how proteins that are comprised of the same amino acids can have very different characteristics and functions. 1911-06-25T00:00:00+0000Bloch was a biochemist who shared the 1964 Nobel Prize for Physiology or Medicine for helping to uncover the mechanism and regulation of cholesterol and fatty acid metabolism. This work laid the foundation for understanding the relationship between blood cholesterol levels and atherosclerosis, a disease in which plaque builds up inside the body's arteries. 1912-01-21T00:00:00+0000A biochemist, Moore helped develop the first automated amino acid analyser in 1958. The machine transformed the ability to analyse the amino acid sequences of proteins. Together with William H Stein, Moore used the machine to determine the amino acid sequence of the ribonuclease molecule. Moore shared the 1972 Nobel Prize for Chemistry for this work. 1913-09-04T00:00:00+0000Perutz fled Austria in 1936 with his Jewish family just after he completed a degree in chemistry at the University of Vienna. Moving to Britain he became involved in X-ray crystallography at the Cavendish Laboratory in Cambridge, using the method to study the structure of proteins. In 1959 he managed to work out the structure of haemoglobin, the protein responsible for transporting oxygen in blood. He was awarded the Nobel Prize for Chemistry for this work in 1962. His research paved the way to understanding how the molecule switches between its deoxygenated and its oxygenated states and oxygen is taken up by muscles and other organs. Pertuz was also the founder and first director of the MRC Laboratory of Molecular Biololgy in Cambridge, set up in 1962.1914-05-19T00:00:00+0000Synge was an English biochemist who shared the 1952 Nobel Prize for Chemistry for the invention of liquid-liquid paper partition chromatography, a technique used to separate mixtures of closely related chemicals such as amino acids. The technique revolutionised analytical chemistry. By 1948 Synge had managed to work out the exact structure of S gramicidin, a simple protein molecule, using the partition technique. Fred Sanger used this work in his elucidation of the structure of insulin in 1955. 1914-10-28T00:00:00+0000Bergstrom was a biochemist who shared the 1982 Nobel Prize for Medicine for isolating and elucidating the chemical structure of prostaglandins which is found in most tissues and organs in humans and mammals. Bergstrom helped show that prostaglandins form from unsaturated fatty acids and their important role in many physiological processes in the body, including causing inflammation after injury or illness, the clotting of blood and uterine contractions. His work revealed that prostaglandins act locally near their site of production, act differently in different tissues and are metabolised very quickly. This opened up new pathways for the treatment of heart disease, strokes and gastric ulcers. It also paved the way to the development of the morning-after pill and inhibitor compounds that help relieve the pain caused by menstruation, gallstones or kidney stones.1916-01-10T00:00:00+0000Kendrew was a biochemist and crystallogapher. He is best known for elucidating the structure of myoglobin, a protein that stores oxygen in muscle cells, for which he shared the Nobel Prize in 1962. In 1963 he helped found the European Molecular Biology Laboratory and later was its director. For many years he was also the editor-in-chief of the Journal of Molecular Biology, 1917-03-24T00:00:00+0000Buchner was a chemist and zymologist. In 1907 he was awarded the Nobel Prize for Chemistry for his discovery of cell-free fermentation. This was based on some experiments he carried out in 1897, during which he found that yeast extract could form alcohol from a sugar solution without any living cells. He discovered that the fermentation was driven by an enzyme, zymase, inside the yeast cells. It provided the first evidence that biochemical processes were driven by enzymes formed inside cells. He was killed in the First World War while serving as a general. 1917-08-13T00:00:00+0000Boyer was a biochemist and analytical chemist renowned for helping to understand the enzymatic mechanism involved in the production of the energy-storage molecule adenosine triphosphate (ATP), which fuels the metabolic processes of all living things. This he did in the 1970s while based at UCLA where he was the founding director of the university's Molecular Biology Institute. In 1997 Boyer was awarded the Nobel Prize for Chemistry for his work on ATP synthesis. 1918-07-31T00:00:00+0000Krebs was a biochemist who in 1933 was forced to leave Nazi Germany because his father was Jewish. He is best known for having discovered two important chemical reactions in the body - the urea cycle and the citric acid cycle. These chemical reactions help break down food molecules into carbon dioxide, water and energy. He made the breakthrough in the 1930s. The process is known as the Krebs cycle. Krebs was awarded the Nobel Prize in 1954.1918-08-25T00:00:00+0000Skou was awarded the Nobel Prize for Chemistry in 1997 for discovering an ion-transporting enzyme called sodium-potassium-activated adenosine triphosphatase (Na+-K+ ATPase), which is found in the plasma membrane of animal cells. The enzyme is important to the transport of molecules through a cell's membrane. Skou made the discovery in the late 1950s. A number of other similar ATPase-based enzymes were discovered later, including one that helps control muscle contraction. 1918-10-08T00:00:00+0000Horwitz was a chemist who is best known for having synthesised the compound zidovudine (commonly called AZT). Originally Horwitz developed the compound to be an anti-cancer drug in 1964, but it failed to show anticancer activity. Other researchers discovered the drug could prolong the life of AIDS patients. Approved for AIDS in 1987 by the US FDA, AZT transformed AIDS from being a fatal condition into a chronic condition. Horwitz also developed didanosine and stauvidine, antiviral drugs that are used to treat HIV/AIDS.1919-01-16T00:00:00+0000Tsvet was a Russian-Italian botanist who is credited with the invention of adsorption chromatography. He first described the method in 1901. His technique involved using ether and alcohol to extract plant pigments from leaves and then passing the resulting solution through a column of calcium carbonate. The advantage of the process was that it separated pigments into different coloured bands. By using the process Tsvet was able to demonstrate that plants had two forms of chlorophyll and eight additional pigments. Chromatography is now an important laboratory technique for the separation of a mixture. 1919-06-26T00:00:00+0000Fischer was a German chemist who opened up the era of biochemistry by clarifying the structure of sugars and enzymes and elaborating how they were formed. In 1902 he was awarded the Nobel Prize for Chemistry for demonstrating the structure of biological compounds, including sugars proteins and purines. He synthesised many natural occurring molecules for the first time, including glucose, caffeine, and uric acid. In addition, he managed to synthesis several amino acids and created small chains of them as precursors to protein formation. Fisher is also associated with the idea of the 'lock and key' mechanism which is used to explain how enzymes catalyse certain reactions and not others. 1919-07-15T00:00:00+0000Benesch was a biochemist. He is best known for the discovery he made with his wife, Ruth Benesch in 1967 which showed how haemoglobin transports oxygen during respiration. They demonstrated that 2,3-diphosphoglycerate, an organic phosphorous compound, plays a pivotal role in loosening the bonds between haemoglobin and oxygen which improves the flow of oxygen from blood to the tissues. Their work opened up a new era in research on the physiology of respiratory carriage and new insights into sickle-cell anaemia. 1919-08-13T00:00:00+0000Fischer is a biochemist. He is best known for helping to discover and describe reversible protein phosphorylation, a biological and chemical reaction that regulates the activities of cell proteins. This he did with Edwin Krebs at the University of Washington. Their work helped illustrate how life exists at the cellular level. They were both awarded the Nobel Prize for Medicine in 1992.1920-04-06T00:00:00+0000Mitchell was a biochemist who won the 1978 Nobel Prize for Chemistry for helping to show how the enzymes adenosine diphosphate (ADP), is converted into the energy-carrying compound adenosine triphosphate (ATP) in the mitrochondria of living cells. He demonstrated this in the 1960s. 1920-09-29T00:00:00+0000Daly trained as a biochemist and was the first Black American woman to earn a doctorate in chemistry (from Columbia University, 1947). Her early research looked at the effects of cholesterol on the mechanisms of the heart, the effects sugars and other nutrients on the health of the arteries and the impact of advanced aged and hypertension on the circulatory system. This she did at Rockefeller Institute in New York. She subsequently joined Columbia University where she investigated how proteins are produced and organised in the cell.

Ruth was one of the 10,000 Jewish children who escaped Nazi Germany to England as part of the Kindertransport programme. 1925-02-25T00:00:00+0000Rose was a biochemist who shared the 2004 Nobel Prize for Chemistry for contributing to understandings about how cells break down proteins. He first became interested in the puzzle of how cells identify and destroy unwanted proteins in the 1950s. In the late 1970s he showed that ubiquitin, a protein present in countless tissues, helped tag other proteins that needed to be destroyed. It would then attach itself to another protein that was no longer functioning and take it to the proteasome chamber to be broken down and recycled. Rose also helped in the development of a drug to treat multiple myeloma, a blood cancer. The drug works by disrupting the protein disposal mechanism and kills the cancer cells with a pile-up of protein.1926-07-16T00:00:00+0000Schally was an endocrinologist who won the 1977 Nobel Prize for Physiology or Medicine for isolating and synthesising three hormones produced by the hypothalmus in the brain which control the activities of hormone producing glands. The hormones he worked on were TRH (thyrotropin-releasing hormone), LHRH (luteinizing hormone-releasing hormone), and the peptide somatostatin. His work led to recognition of the hypothalmus as the controlling factor of the pituitary gland and opened a new chapter for research into fertility, contraception, diabetes, abnormal growth, mental retardation as well as depression and other mental disorders. 1926-11-30T00:00:00+0000Gilbert is a molecular biologist.

This work laid the foundation for understanding the relationship between blood cholesterol levels and atherosclerosis, a disease in which plaque builds up inside the body's arteries. 2000-10-15T00:00:00+0000Perutz fled Austria in 1936 with his Jewish family just after he completed a degree in chemistry at the University of Vienna. Moving to Britain he became involved in X-ray crystallography at the Cavendish Laboratory in Cambridge, using the method to study the structure of proteins. In 1959 he managed to work out the structure of haemoglobin, the protein responsible for transporting oxygen in blood. He was awarded the Nobel Prize for Chemistry for this work in 1962. His research paved the way to understanding how the molecule switches between its deoxygenated and its oxygenated states and oxygen is taken up by muscles and other organs. Pertuz was also the founder and first director of the MRC Laboratory of Molecular Biololgy in Cambridge, set up in 1962. 2002-02-06T00:00:00+0000Daly trained as a biochemist and was the first Black American woman to earn a doctorate in chemistry (from Columbia University, 1947). Her early research looked at the effects of cholesterol on the mechanisms of the heart, the effects sugars and other nutrients on the health of the arteries and the impact of advanced aged and hypertension on the circulatory system. This she did at Rockefeller Institute in New York. She subsequently joined Columbia University where she investigated how proteins are produced and organised in the cell. In addition to her scientific work, Daly was an ardent campaigner for getting minority students into medical school and graduate science programmes.2003-10-28T00:00:00+0000Bergstrom was a Swedish biochemist who shared the 1982 Nobel Prize for Medicine for isolating and elucidating the chemical structure of prostaglandins which is found in most tissues and organs in humans and mammals. Bergstrom helped show that prostaglandins form from unsaturated fatty acids and their important role in many physiological processes in the body, including causing inflammation after injury or illness, the clotting of blood and uterine contractions. His work revealed that prostaglandins act locally near their site of production, act differently in different tissues and are metabolised very quickly. This opened up new pathways for the treatment of heart disease, strokes and gastric ulcers. It also paved the way to the development of the morning-after pill and inhibitor compounds that help relieve the pain caused by menstruation, gallstones or kidney stones.2004-08-15T00:00:00+0000Merrifield was an American biochemist and organic chemist. In 1984 he was awarded the Nobel Prize for Chemistry for inventing a process known as solid phase peptide synthesis. He developed the technique in 1965. It provided a methodology for chemical synthesis on a solid matrix. By the mid-1960s he and his team had proved the method could be used to synthesise bradykinin, angiotensin, desamino-oxytocin and insulin. In 1969 they managed to synthesise the enzyme, ribonuclease A. This was the first proof of the chemical nature of enzymes. Merrifield's method is now a rountine method for automatically synthesising large proteins, novel nucleotides, or short fragments of DNA. 2006-05-14T00:00:00+0000Horwitz was an American chemist who is best known for having synthesised the compound zidovudine (commonly called AZT). Originally Horwitz developed the compound to be an anti-cancer drug in 1964, but it failed to show anticancer activity. Other researchers discovered the drug could prolong the life of AIDS patients. Approved for AIDS in 1987 by the US FDA, AZT transformed AIDS from being a fatal condition into a chronic condition. Horwitz also developed didanosine and stauvidine, antiviral drugs that are used to treat HIV/AIDS.2012-09-06T00:00:00+0000Levi-Montalcini is best known for sharing the Nobel Prize in 1986 for helping to discover and isolate the nerve growth factor which helps regulate the growth, maintenance, proliferation and survival of certian neurons. Banned by Mussolini from working in academia because she was Jewish, Levi-Montalcini conducted much of her early work in a makeshift laboratory in her bedroom. She later became the director of the Research Center of Neurobiology and the Laboratory of Cellular Biology in Washington University and founded the European Brain Research Institute. 2012-12-30T00:00:00+0000Rose was an American biochemist who shared the 2004 Nobel Prize for Chemistry for contributing to understandings about how cells break down proteins. He first became interested in the puzzle of how cells identify and destroy unwanted proteins in the 1950s. In the late 1970s he showed that ubiquitin, a protein present in countless tissues, helps tag other proteins that need to be destroyed. It then attaches itself to another protein that is no longer functioning and takes it to the proteasome chamber to be broken down and recycled. Rose also helped develop a drug to treat multiple myeloma, a blood cancer. The drug works by disrupting the protein disposal mechanism and kills the cancer cells with a pile-up of protein. 2015-06-03T00:00:00+0000Tsien was a Chinese-American biochemist who shared the 2008 Nobel Prize for Chemistry for the discovery and development of genetically programmable fluorescent tags. These multicoloured fluorescent proteins, developed in Tsien's laboratory between 1994 and 1998, provide a means to observe in real-time different phenomena in living cells and organisms, including gene expression, protein-protein interactions, cell division, chromosome replication and organisation, intracellular pathways, organelle inheritance and biogenesis.2016-08-26T00:00:00+0000Skou was a Danish biochemist who was awarded the Nobel Prize for Chemistry in 1997 for discovering an ion-transporting enzyme called sodium-potassium-activated adenosine triphosphatase (Na+-K+ ATPase), which is found in the plasma membrane of animal cells. The enzyme is important to the transport of molecules through a cell's membrane. Skou made the discovery in the late 1950s. A number of other similar ATPase-based enzymes were discovered later, including one that helps control muscle contraction.2018-05-28T00:00:00+0000Boyer was an American biochemist and analytical chemist renowned for helping to understand the enzymatic mechanism involved in the production of the energy-storage molecule adenosine triphosphate (ATP), which fuels the metabolic processes of all living things. This he did in the 1970s whle based at UCLA where he was the founding director of the university's Molecular Biology Institute. In 1997 Boyer was awarded the Nobel Prize for Chemistry for his work on ATP synthesis.2018-06-02T00:00:00+0000
