Pyruvate (CH3COCOO−) is the ionized form of pyruvic acid. It is an important chemical compound in biochemistry. It is the output of the breakdown of glucose known as glycolysis, and (in aerobic respiration) the main input for the citric acid cycle via acetyl CoA. It can be converted to oxaloacetate, an intermediate of the TCA cyle by an anaplerotic reaction. In anaerobic respiration, pyruvate from glycolysis can be converted to lactate using the enzyme lactate dehydrogenase and the coenzyme NADH (in lactate fermentation), or to acetaldehyde and then to ethanol (in alcoholic fermentation).de:Pyruvat fr:Pyruvate
