Blood cells stored in a blood bank lose 2,3-diphosphoglycerate, but once they are infused, the substance is resynthesized or reactivated. Medical Dictionary, © 2009 Farlex and Partners 2,3-Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), promotes hemoglobin transition from a high-oxygen-affinity state to a low-oxygen-affinity state. The 2,3-BPG binds to the central compartment of the hemoglobin tetramer, changing its conformation and shifting the oxygen dissociation curve to the right. Definition 2,3-diphosphoglycerate (2,3-DPG) is a substance made in the red blood cells. It controls the movement of oxygen from red blood cells to body tissues. 2,3-DPG testing is done to help investigate both a deficiency in red blood cells (anemia) and an unexplained increase of red blood cells, called erythrocytosis. 2,3-diphosphoglycerate (2,3-DPG) is a chemical normally present in relatively small amounts in red blood cells.
Förhöjda värden ses alltså vid akut acidos, Teoretiska fördelar är prevention mot respiratorisk utmattning och produktion av 2-3 DPG. De patienter man då skulle tänka sig substituera är Fosfat och dextrose krävs för att upprätthålla erytrocyternas metabolism så att de energirika föreningarna ATP och 2,3-DPG kan bildas. Lagrat blod kommer successivt att minska koncentrationen av 2,3-DPG för att vid 14 dagars lagring vara i princip omätbart.

2,3-diphosphoglycerate (2,3-DPG) in red blood cells (RBC) determines the ease with which hemoglobin releases oxygen in the tissues. The higher the level of erythrocytic 2,3DPG, the lower is the affinity to oxygen and vice versa. pH levels during acid-base disorder influence oxygen affinity by affecting both 2,3-DPG metabolism and oxyhaemoglobin dissociation curve.

The BPGM gene encodes the enzyme 2,3-bisphosphoglycerate mutase (BPGM) that catalyzes the conversion of 1,3-bisphosphoglycerate to 2,3-bisphosphoglycerate (2,3-BPG), also known as 2,3-diphosphoglycerate (2,3-DPG), through the Luebering-Rapoport pathway. 2,3-BPG is a small molecule generated from glycolysis and is present in large amounts in red blood cells.
