Oxygen equilibrium characteristics of adult and fetal hemoglobin of Japanese monkey (Macaca fuscata).
Adult hemoglobin and fetal hemoglobin were obtained from Japanese monkey (Macaca fuscata) and their oxygen equilibrium characteristics were studied. (1) The oxygen affinity of fetal hemoglobin was higher than that of adult hemoglobin both in the presence and absence of 2,3-diphosphoglycerate. The presence of diphosphoglycerate lowers the oxygen affinity of adult hemoglobin much greater than does that of HbF and the diphosphoglycerate levels of red cells of adult and newborn monkeys are about the same. (2) The intensity of the Bohr effect, as expressed by -deltalogP50/deltapH, at pH 7.4 was in the order of fetal hemoglobin-diphosphoglycerate greater than adult hemoglobin-diphosphoglycerate greater than fetal hemoglobin greater than adult hemoglobin.
