| Common Name | 3-Phosphoglyceric acid |
|---|
| Description | 3-Phosphoglyceric acid, also known as 3PG, belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. 3PG is the conjugate acid of glycerate 3-phosphate (GP or G3P). It is a solid that is soluble in water. 3-Phosphoglyceric acid exists in all living species, ranging from bacteria to humans. The glycerate is a biochemically significant metabolic intermediate in both glycolysis and the Calvin cycle. This is the first compound formed during the C3 or Calvin cycle. Glycerate 3-phosphate is also a precursor for serine, which, in turn, can create cysteine and glycine through the homocysteine cycle. Within humans, 3-phosphoglyceric acid participates in a number of enzymatic reactions. In particular, 3-phosphoglyceric acid can be biosynthesized from glyceric acid 1,3-biphosphate, which is mediated by the enzyme phosphoglycerate kinase 1. In addition, 3PG can be converted into 2-phospho-D-glyceric acid, which is catalyzed by the enzyme phosphoglycerate mutase 2. 3-Phosphoglyceric acid is involved in the Warburg effect (aerobic glycolysis), a metabolic shift that is a hallmark of cancer (PMID: 29362480 ). |
