'''Glycerate 3-phosphate (GP)''' or '''3-phosphoglycerate (3PG)''' is a [[biochemistry|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 CO<sub>2</sub>.

==Calvin cycle==
In the Calvin cycle, two glycerate 3-phosphate molecules are reduced to form two molecules of [[glyceraldehyde 3-phosphate]] (PGAL). This is the first compound formed during the C3 or Calvin cycle. It is a reactive biomolecule which 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.
