2,3-diphosphoglycerate (2,3-DPG) is a chemical normally present in relatively small amounts in red blood cells. Its job is to change how oxygen binds to hemoglobin in order to make oxygen fall off of hemoglobin more easily so that when a red blood cell passes through vital organs (like the brain), more oxygen can be released by that red blood cell.

Quantitatively, 2,3-DPG is the major glycolytic intermediate in the red blood cell and its levels are about equal to the sum of the other glycolytic intermediates. 1 Enzyme deficiencies proximal to the 2,3-DPG step (ie, PGK and PK deficiency) show increased 2,3-DPG levels as a result of the respective metabolic blocks and of a retrograde accumulation of products of glycolysis. 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. 2,3-DPG alters the oxygen affinity of haemo- globin, such that an increase in the intra- erythrocytic 2,3-DPG concentration reduces the affinity of haemoglobin for oxygen and vice-versa. Therefore an increase in 2,3-DPG concentration improves tissue oxygenation whereas a decrease in 2,3-DPG concentration 2009-07-09 Human 2, 3-Disphosphoglycerate (2, 3-DPG) ELISA Kit Catalog Number.

However, when hypoxia is encountered in peripheral tissues, the concentration of 2,3-DPG can accumulate to significant levels within hours. 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.

2,3-DPG An organic phosphate in red blood cells that alters the affinity of hemoglobin for oxygen. 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-Diphosphoglycerate (2,3-DPG) is a special intermediate of glycolysis in erythrocytes which is rapidly consumed under conditions of normal oxygen tension. However, when hypoxia is encountered in peripheral tissues, the concentration of 2,3-DPG can accumulate to significant levels within hours. 2,3-DPG: An inorganic phosphate produced in red cells by the Rapoport-Luebering shunt; 2,3-DPG binds to the beta chain of reduced haemoglobin (Hb), lowering Hb's affinity for O2 and by extension, facilitating O2 release to tissues, causing a "right shift" of the O2 dissociation curve. 2,3-DPG further shifts the curve to the right by lowering 2,3-DPG levels are important in large blood transfusions, because stored blood quickly loses 2,3-DPG and its ability to deliver oxygen. After transfusion, the red cells rebuild the 2,3-DPG, but it takes about 24 hours to regain a normal level of 2,3-DPG and hemoglobin function.
