Meaning and Definition
A phosphorylated derivative of glycerate, specifically 2,3-diphosphoglycerate, which plays a crucial role in regulating the oxygen-binding affinity of hemoglobin in red blood cells.
In biochemistry, it refers to any ester of diphosphoglyceric acid. Its primary biological form, 2,3-Bisphosphoglycerate (2,3-BPG), is a key allosteric effector modulating hemoglobin function and is an intermediate in the glycolytic pathway.

- Mispronunciation: stressing the wrong syllable (e.g., diphosphoGLYcerate).
- Incorrect abbreviation: using 'DPG' without the '2,3-' prefix can be ambiguous.
FAQ
Frequently Asked Questions
It acts as an allosteric effector in red blood cells, binding to hemoglobin and decreasing its affinity for oxygen, thereby promoting oxygen release to tissues.
No, it is found in most mammals and many other organisms, though its role and concentration can vary.
Stored blood loses 2,3-BPG over time. Low levels mean transfused red cells have a higher oxygen affinity initially, which can temporarily impair oxygen delivery until the cells regenerate 2,3-BPG.
Di- (two) + phospho- (phosphate group) + glycerate (the three-carbon backbone derived from glycerol/glyceric acid).
A phosphorylated derivative of glycerate, specifically 2,3-diphosphoglycerate, which plays a crucial role in regulating the oxygen-binding affinity of hemoglobin in red blood cells.
