Iron absorption into mucosal cells of the gut is a simple diffusion process. Hemosiderin is produced by denaturation of ferritin with the loss of some apoprotein. Apotransferrin is a large protein complex capable of binding thousands of iron hydroxide molecules. Iron is transported in blood chiefly as part of ferritin. Oxidizing agents promote the absorption of iron from the intestine.
