Like adult hemoglobin, fetal hemoglobin is in equilibrium with oxygen. However, the equilibrium
constant for fetal hemoglobin is
the equilibrium constant for adult hemoglobin, meaning
that the reaction tends to go farther in the direction of the product. Consequently, fetal hemoglobin
loads oxygen at a
oxygen concentration than adult hemoglobin. In the placenta, fetal
blood flows in close proximity to maternal blood, without the two ever mixing. Because of
equilibrium constants, the maternal hemoglobin unloads oxygen which the fetal
hemoglobin then binds and carries into its own circulatory system. Nature has thus evolved a chemical
system through which the mother's hemoglobin can in effect hand off oxygen to the hemoglobin of the
fetus.
