Provided nonheme iron is often current in the form of ferric iron, it needs to be reduced on the ferrous kind just before enterocyte uptake Together with the ferric reductase enzyme DCYTB. The apical floor in the enterocyte has divalent metallic transporter 1 (DMT1), which transports ferrous iron in to the enterocyte. About the basolateral membrane of your enterocyte, ferroportin releases ferrous iron to hephaestin, which oxidizes ferrous iron to ferric iron so it may bind to the transporting protein transferrin in portal circulation.
