2.3-Diphosphoglycerate degradation kinetics was studied under conditions of human erythrocyte depletion, using the method of 31P-NMR of high performance. The kinetic curve was shown to have a plateau during the first 1.5-2 hours after the beginning of depletion. Possible mechanisms providing for the appearance of such a plateau are discussed.

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture

D019794	2,3-Diphosphoglycerate	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).
