Extractions: Merrifield, Robert Bruce Bruce Merrifield was born in Fort Worth, Texas, July 15, 1921, the only son of George E. and Lorene (Lucas) Merrifield. In the spring of 1923 they drove across the southwest desert to settle in California where they lived in several cities throughout the state. He attended nine grade schools and two high schools before graduating from Montebello High School in 1939. His interest in chemistry began there and he also enjoyed the astronomy club where he ground a mirror and built a small reflecting telescope. From Les Prix Nobel 1984.

Z amerikanischer Biochemiker, geboren 15.7.1921 Fort Worth (Tex.); ab 1949 Mitarbeiter des biochemischen Labors des Rockefeller Institute for Medical Research in New York, seit 1966 Professor in New York; entwickelte 1962 ein Verfahren zur chemischen Synthese von Peptiden und Proteinen, bei dem die wachsenden Ketten während der Synthese an eine feste Matrix (z.B. Polystyrol) gebunden sind (Festphasensynthese); baute auf der Basis dieses Verfahrens 1965 mit seinen Mitarbeitern den Prototyp eines Syntheseautomaten, mit dem die (oft Monate betragende) Synthesedauer auf 1/50 der sonst benötigten Zeit verkürzt werden konnte; das auch als Merrifield-Synthese bezeichnete Verfahren, das 1969 erstmals zur Totalsynthese eines enzymatisch aktiven Proteins (Ribonuclease, bestehend aus 124 Aminosäuren) führte, konnte später auch auf die chemische Synthese von Polynucleotiden ausgedehnt werden; erhielt 1984 den Nobelpreis für Chemie.

Merrifield, Robert Bruce Robert Bruce Merrifield (July 15, 1921 – May 14, 2006) was an American biochemist who won the Nobel Prize in Chemistry in 1984 for the invention of solid phase peptide synthesis.1 http://www.cartage.org.lb/fr/themes/Biographies/mainbiographie/M/Merrifield/Merr
Extractions: En 1959 débute l'aventure qui le mènera au prix Nobel de chimie. Il y a eu, avant Merrifield, nous l'avons vu, d'autres lauréats du prix Nobel à avoir travaillé sur la synthèse des peptides, le premier d'entre eux ayant été Emil Fischer. Mais la date marquante reste l'année 1953 où a été réussie, par Vincent du Vigneaud la synthèse de l'oxytocine. La synthèse d'un peptide nécessite plusieurs étapes successives durant lesquelles s'enchaînent les différents acides animés. Opérer en milieu liquide, comme l'avait fait du Vigneaud, soulève d'énormes difficultés, car il faut à chaque étape isoler et purifier les intermédiaires de la réaction. Merrifield chercha donc à simplifier la méthode de synthèse; c'est en 1963 qu'il publie ses expériences, dévoilant la nouvelle méthode de synthèse des peptides sur support solide. Cette méthode va rapidement dépasser le cadre de la synthèse peptidique, et avoir une portée générale en chimie organique, tout particulièrement dans la synthèse des polymères. Le grand mérite de Merrifield et de ses collaborateurs a été de réaliser un appareil automatique, programmé, qui peut avec des rendements élevés produire de façon répétitive les différentes étapes chimiques permettant l'addition de chaque aminoacide à une chaîne polypeptidique qui croît progressivement. Une séquence programmée de réactions s'effectue dans un seul réacteur, à l'aide de pompes calibrées, avec des réactifs ajoutés automatiquement à partir d'un réservoir: l'appareil tient compte des temps de réaction de chaque étape et, grâce à la "technique en phase solide", sépare les produits de la réaction des substances parasites.

Nobel Prize in Chemistry winners Robert Bruce Merrifield is an American biochemist He was born in Fort Worth Texas 15 July , the only son of George E. Merrifield and Lorene née Lucas. In the family moved to California where he attended nine grade schools and two high schools before graduating from Montebello High School in . It was there that he developed an interest both in chemistry and in astronomy After two years at Pasadena Junior College he transferred to the University of California at Los Angeles (UCLA). After graduation in chemistry he worked for a year at the Philip R. Park Research Foundation taking care of an animal colony and assisting with growth experiments on synthetic amino acid diets. One of these was the experiment by Geiger that first demonstrated that the essential amino acids must be present simultaneously for growth to occur.

July 15 , 1921 in Fort Worth, Texas May 14 , 2006 in Cresskill, New Jersey Merrifield was an American biochemist who invented the process of solid phase peptide synthesis. Peptides would be built one amino acid at a time on a substrate of polymer to form custom chains and then the substrate would be chemically removed. This technique would earn him the 1984 Nobel Prize in Chemistry. Related Articles Guide since 2001 Anne Marie Helmenstine, Ph.D.

Extractions: The proud Merrifield family originated in Cornwall , a rugged coastal region in southwestern England . In early times, people were known by only a single name. However, as the population grew and people travelled further afield, it became increasingly necessary to assume an additional name to differentiate between bearers of the same personal name. The manner in which hereditary surnames arose is interesting.
