D-(-)-3-Phosphoglyceric acid (3-Phospho-D-glyceric acid) disodium is an important intermediate in the enzyme-catalyzed glycolysis process. D-(-)-3-Phosphoglyceric acid disodium competitively inhibits yeast enolase (enolase). D-(-)-3-Phosphoglyceric acid disodium can regulate the activity of phosphoglycerate dehydrogenase (PHGDH) to modulate p53 protein and apoptosis[1][2][3].
