Sir Hans Adolf KrebsDied 22 Nov 1981 at age 81 (born 25 Aug 1900). German-British biochemist who shared (with Fritz Lipmann) the 1953 Nobel Prize for Physiology or Medicine for the discovery in living organisms of the series of chemical reactions known as the tricarboxylic acid cycle (also called the citric acid cycle, or Krebs cycle)—the basic system for the essential pathway of oxidation process within the cell. These reactions involve the conversion—in the presence of oxygen—of substances that are formed by the breakdown of sugars, fats, and protein components to carbon dioxide, water, and energy-rich compounds. The Krebs cycle explains two simultaneous processes: the degradation reactions which yield energy, and the building-up processes which use up energy. |
