2,3-Diphosphoglyceric acid (pentasodium)

2,3-Diphosphoglyceric acid (2,3-DPG) pentasodium is an intermediate of the glycolytic pathway. 2,3-Diphosphoglyceric acid pentasodium stabilizes the deoxygenated form of hemoglobin by allosteric binding and facilitates oxygen release at tissue sites. 2,3-Diphosphoglyceric acid pentasodium binds to hemoglobin and decrease its affinity for oxygen[1][2].
