3-Phosphoglyceric acid (3PG), or glycerate 3-phosphate (GP), is a biochemically significant 3-carbon molecule that is a metabolic intermediate in both glycolysis and the Calvin cycle. This chemical is often termed PGA when referring to the Calvin cycle. In the Calvin cycle, 3-Phosphoglycerate is the product of the spontaneous split of an unstable 6-carbon intermediate formed by CO2 fixation. Thus, two 3-phosphoglycerate molecules are produced for each molecule of CO2 fixed.

Calvin cycle

In the light-independent reactions (also known as the Calvin cycle), two 3-phosphoglycerate molecules are synthesized, one of which continues through the Calvin cycle to be regenerated to Rubisco and the other is reduced to form one molecule of glyceraldehyde 3-phosphate (G3P). This is the first compound formed during the C3 or Calvin cycle. It is a reactive biomolecule that is easily reduced.

Amino acid synthesis

Glycerate 3-phosphate is also a precursor for serine, which, in turn, can create cysteine and glycine through the homocysteine cycle.
