Design, synthesis, and activity of 2,3 …
Patients over 1 month of age with arterial oxygen pressures of less than 60 mm Hg were found to have elevated red cell 2,3-diphosphoglycerate (2,3-DPG) levels and blood with a decreased affinity for oxygen. The increase in 2,3-DPG was proportional to the degree of hypoxemia. In patients under 1 month of age this relationship was not observed. Red cells from adults, but not newborns, showed rapid increases in 2,3-DPG when incubated under nitrogen. Adult, but not fetal, deoxyhemoglobin was shown to facilitate in vitro synthesis of 2,3-DPG by binding this organic phosphate and relieving the product inhibition of 2,3-DPG mutase.

Where the O tension is low, as in the venous blood, the Bohr effect and 2,3-DPG combine to reduce the affinity of Hgb for O , releasing O to tissues.

Incubation of adult and fetal red blood cells in a medium containing high concentrations of inorganic phosphate showed a different response in the synthesis of 2,3 diphosphoglycerate. This was increased only in fetal red cells, while an evident increase in fructose 1,6 diphosphate was seen in both adult and fetal red blood cells.
