Cori, Carl Ferdinand
Born Dec. 5, 1896, in Prague. American biochemist; member of the US National Academy and the Royal Society of London.
Cori graduated from the University of Prague in 1920. He joined the State Institute for the Study of Malignant Disease in Buffalo (USA) in 1922. He became a professor of biochemistry and pharmacology at the Washington University School of Medicine in St. Louis in 1931. Cori’s main work, conducted with the assistance of his wife, Gerty Teresa Radnitz-Cori (born Aug. 15, 1896, in Prague; died Oct. 26, 1957, in St. Louis), has been devoted to the study of carbohydrate metabolism in animals. He discovered and isolated glucose-1-phosphate, or Cori ester, and discovered and investigated phosphoglucomutase, which catalyzes the reversible conversion of glucose-l-phosphate into glucose-6-phosphate. Cori isolated phosphorylase and studied the interconversion of phosphorylase A and phosphorylase B. He discovered transglucosidase, and he obtained phosphoglucomutase, glyceraldehydephosphate dehydrogenase, and aldolase from muscles in crystal form. He extracted pure hexokinase from yeast. Cori carried out a series of studies on the effect of hormones on enzymatic processes. He separated glucagon from insulin and extracted it from gastric mucosa. Cori was awarded the Nobel Prize in 1947 (jointly with G. Cori).
