phosphoenol pyruvate

/phos·pho·enol ·py·ru·vate/ (-e″nol-pi´roo-vāt) a high energy derivative of pyruvate occurring as an intermediate in the Embden-Meyerhof pathway of glucose metabolism, in gluconeogenesis, and in the biosynthesis of some amino acids.

phosphoenolpyruvic acid or phosphoenolpyruvate (PEP)

a high-energy compound which when dephosphorylated to pyruvic acid, gives rise to the synthesis of ATP from ADP in GLYCOLYSIS.


an intermediary metabolite in the Embden-Myerhof glycolytic pathway; abbreviated PEP.
