Web12.72 Iron Transport & Storage. Transferrin is the major iron transport protein (transports iron through blood). Fe3+ is the form of iron that binds to transferrin, so the Fe2+ transported through ferroportin must be oxidized to Fe3+. There are 2 copper-containing proteins that catalyze this oxidation of Fe2+: hephaestin and ceruloplasmin. WebThe absorption of most dietary iron occurs in the duodenum and proximal jejunum and depends heavily on the physical state of the iron atom. At physiological pH, iron exists in the oxidized, ferric (Fe3+) state. To be absorbed, iron must be in the ferrous (Fe2+) state or bound by a protein such as heme.
