WebIron is an essential bioelement for most forms of life, from bacteria to mammals. Its importance lies in its ability to mediate electron transfer. In the ferrous state (Fe 2+ ), iron acts as an electron donor, while in the ferric state (Fe 3+) it acts as an acceptor. WebDietary iron is absorbed through the mucosal cells as ferrous (Fe ++) form. Iron in diet is mostly present as ferric (Fe +++) state which is reduced to ferrous form during’ absorption. Vitamin C, glutathione and amino acid-SH groups help in reduction of ferric to ferrous form. After entering the mucosal cell as ferrous form, the iron ...
