Glyceric acid refers to

chiral. Salts and esters
of glyceric acid are known as glycerates.

Production

Glyceric acid is usually produced by oxidation of glycerol. A typical oxidant is nitric acid, but catalytic oxidations have been developed also:[2][3]

HOCH2CH(OH)CH2OH + O2 → HOCH2CH(OH)CO2H + H2O

As glycerol is

prochiral, the oxidation of the two terminal alcohol groups gives distinct enantiomers of glyceric acid. Oxidation of both primary alcohols gives tartronic acid
:

HOCH2CH(OH)CH2OH + 2 O2 → HO2CCH(OH)CO2H + 2 H2O

Biochemistry

Several

1,3-bisphosphoglyceric acid, are intermediates in glycolysis.[4] 3-Phosphoglyceric acid is an intermediate in the biosynthesis of the amino acid serine, which in turn can be used in the synthesis of glycine and cysteine.[5]

Glyceric acid occurs naturally in Populus tremula and Ardisia crenata.[6]
