Metabolite Identification
Common Name2-Phosphoglyceric acid
Description2-Phosphoglyceric acid belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. 2-Phosphoglyceric acid (2PGA) is a glyceric acid which serves as the substrate in the ninth step of glycolysis. This intermediate is created by removal of the proton from C2 of 2PGA by a base in the active site. It is catalyzed by enolase into phosphoenolpyruvate (PEP), the penultimate step in the conversion of glucose to pyruvate. 2-Phosphoglyceric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Phosphoglyceric acid exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 2-Phosphoglyceric acid has been detected, but not quantified in, milk (cow). This could make 2-phosphoglyceric acid a potential biomarker for the consumption of these foods. Enolase catalyzes the beta-elimination reaction in a stepwise manner wherein OH- is eliminated from C3 of a discrete carbanion (enolate) intermediate.
