Name: 3-Phosphoglycerate
Description:3-phosphoglyceric acid (3PG) is a 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, two glycerate 3-phosphate molecules are reduced to form two molecules of glyceraldehyde 3-phosphate (GALP).
