title: [Metabolism of the organic phosphate regulators of oxygenation in cells of the erythrocyte series in birds and mammals].
abstract: In mammals, bisphosphoglycerate-synthase activity, whose assay methods are previously discussed, increases gradually along erythropoiesis, leading to a consequent enhancement of 2,3-bisphosphoglycerate formation. Avian erythrocytes, on the other hand, contain inositol-pentaphosphate as major organic phosphate starting from egg eclosion, which substitutes embrionary ATP and 2,3-BPG in the regulatory function. The IHP of phytase and the disappearance of 2,3-BPG synthesis, also inhibitor of enzyme activity, should be considered responsible for IPP accumulation.
