Biochem/physiol Actions
Metabolite of glycolysis within human erythrocytes produced by 2,3-diphosphoglycerate mutase in an alternative to the glycolytic pathway. Binds to hemaglobin to reduce oxygenation.
Application
D-Glycerate 2,3-diphosphate, cofactor of both phosphoglyceric acid mutase and hemoglobin, may be used as a reference compound in analysis of blood cell (erythrocyte) glycolysic cycle metabolites.
