Glycerate 3-phosphate (GP) or 3-phosphoglycerate (3PG) 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. 3-phosphoglycerate is the resultant of the split of 6 carbon intermediate that is so unstable it splits instantly. And two 3-phosphoglycerate is produced for each molecule of CO2.
