The carboxylate (COOH) ion (anion) of pyruvic acid, CH3COCOO-,'s known as pyruvate, and's a key intersection in several metabolic pathways. It can be made from glucose through glycolysis, supplies energy to living cells in the citric acid cycle, and can also be converted to carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to t… (More on Pyruvate)
