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.[citation needed] 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.
