Identification
Name: 2-Phospho-D-glyceric acid
Description:2-Phospho-D-glycerate or 2PG is an intermediate in gluconeogenesis. It is a glyceric acid which serves as the substrate in the ninth step of glycolysis. 2PG is converted by enolase into phosphoenolpyruvate (PEP), the penultimate step in the conversion of glucose to pyruvate. More specifically, 2PG can be generated from Glycerate-3-phosphate via phosphoglycerate mutase or from phosphoenolpyrvate via alpha enolase.
