Iron Absorption

Iron is brought into the cell through an active transport process involving the protein DMT1 (divalent metal transporter1), which is expressed on the apical surface of enterocytes in the initial part of the duodenum. DMT1 is not specific to iron, and can transport other metal ions such as zinc, copper, cobalt, manganese, cadmium or lead.
