Glycerate 2,3-Bisphosphate | 《英文msh词典》Glycerate 2,3-Bisphosphate | | [入口词] Glycerate 2,3-Bisphosphate | | [主题词] 2,3-Diphosphoglycerate | | [英文释义] A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as hemoglobin. It binds to deoxyhemoglobin but not the oxygenated form,therefore diminishing the oxygen affinity of hemoglobin. This is essential in enabling hemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1).
