The oxygen Bohr effect of human fetal hemoglobin has been studied both in terms of oxygen equilibrium at constant pH and of differential titrations. Fetal and adult hemoglobins have the same normal but different reverse Bohr effects, the reverse effect in fetal hemoglobin being only about half that of adult hemoglobin. The heme-heme interactions are the same for the two proteins, the value of n being equal to 2.9 ± 0.2 over the entire pH range examined.
