Fritz Albert Lipmann (1899–1986), an American biochemist who was awarded, jointly with H. A. Krebs, the 1953 Nobel Prize in Physiology or Medicine for his contribution to our understanding of how cells convert food into energy. He discovered that coenzyme A acted as a crucial intermediary catalytic substance in carbohydrate oxidation. Coenzyme A is one of the most important substances in cellular metabolism; it aids the conversion of amino acids, steroids, fatty acids, and hemoglobin into energy.
