WebIron is transported out of the enterocyte and into portal blood via ferroportin (SLC40A1) located on the basolateral membrane. Ferroportin transports only Fe2+, whereas transferrin in portal blood will bind only Fe3+. Efficient transfer of iron to portal blood transferrin is thought to involve an oxidation step catalyzed by a ferroxidase.
