2-Phosphoglyceric acid is a chemical compound from the group of phosphorylated hydroxycarboxylic acids .
Isomers
There are two stereoisomeric forms of 2-phosphoglyceric acid, the naturally occurring D -2-phosphoglyceric acid [synonym: ( R ) -2-phosphoglyceric acid] and the practically meaningless enantiomer L -2-phosphoglyceric acid.
Biological function
Of particular importance is D -2-phosphoglycerate , which is present as an anion under physiological conditions and is an intermediate in glycolysis and gluconeogenesis . The conversion to D - 3-phosphoglycerate takes place through the phosphoglycerate mutase . They also catalyze the reverse reaction . The enzyme enolase converts D -2-phosphoglycerate into phosphoenolpyruvate and water. This reaction is also reversible.
