Phosphoénol pyruvate

See also: PEP

The phosphoénol pyruvate (PEP) is an important compound of the cellular Biochimie. This molecule has three carbon atoms is an intermediary of the Glycolyse and Néoglucogenèse. It is also met in the reactions of the obscure phase of the Photosynthèse.

The PEP has a bond énol-phosphate rich in energy, it is thus a compound with high natural energy. The hydrolysis of this connection releases approximately 56 kJ/mol.

In glycolysis, the PEP is cleaved by the Pyruvate kinase by forming pyruvate and a molecule of ATP (by transfer of the radical phosphoryl to a molecule of ADP).
