Pyruvic Acid

Pyruvic acid (CH3COCOOH) is an organic acid, a ketone, as well as the simplest of the alpha-keto acids. The carboxylate (COO−) anion of pyruvic acid, its Brønsted–Lowry conjugate base, CH3COCOO−, is known as pyruvate, and is a key intersection in several metabolic pathways.

Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through acetyl-CoA. It can also be used to construct the amino acid alanine and be converted into ethanol.

Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactic acid when oxygen is lacking (fermentation).
