摘要：

1. 1. The activities of the enzymes and intracellular concentrations of substrates and cofactors associated with phosphoglyceric acid metabolism in erythrocytes of nine mammals are reported. 2. 2. In every case 2,3-DPG phosphatase activity was lower than that of the other enzymes measured: glyceraldehyde phosphate dehydrogenase, diphosphoglycerate mutase, phosphoglycerate kinase and phosphoglycerate mutase. 3. 3. The red blood cells of man, rabbit, dolphin and pig contain high concentrations of 2,3-DPG and ATP whereas bovine, caprine and feline erythrocytes contain little of either compound. Equine erythrocytes contain large amounts of 2,3-DPG but little ATP. 4. 4. No 2,3-DPG and only very small amounts of diphosphoglyceric acid mutase was detected in the erythrocytes of the goat. © 1969.
