Phospho(enol)pyruvic acid (PEP) acts as an inhibitor of hexokinase, phosphoglucose isomerase, phosphofructokinase and aldolase. It is a bifunctional carbohydrate, which exhibits antioxidant property. PEP may be a potential organ preservation agent in clinical transplantation.

Biochem Physiol Actions: Phospho(enol)pyruvic acid (PEP) is involved in glycolysis and gluconeogeneis. In glycolysis, PEP is metabolized by Pyruvate Kinase to yield pyruvate. In plants, PEP is involved in the formation of aromatic amino acids as well as in the carbon fixation pathway.
