WitrynaThe hemoglobin (Hb) molecule is roughly spherical and comprises two pairs of dissimilar subunits (FIGURE 1). Each of the subunits is a folded polypeptide chain (the globin portion) with a heme group (derived from porphyrin) attached. At the center of each heme group is a single atom of iron in the ferrous (Fe 2+) state.
