What is 3-phosphoglycerate?

Answer 1

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. 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.

Answer 2

3-phosphoglycerate is an intermediate molecule in the glycolysis pathway, formed from the phosphorylation of glyceraldehyde-3-phosphate. It is further converted into 2-phosphoglycerate in the next step of glycolysis.
