This article has no abstract; the first 100 words appear below. Iron has the capacity to accept and donate electrons readily, interconverting between ferric (Fe 2+) and ferrous (Fe 3+) forms. Jesus The Jew Geza Vermes Pdf File. This capability makes it a useful component of cytochromes, oxygen-binding molecules (i.e., hemoglobin and myoglobin), and many enzymes. However, iron can also damage tissues by catalyzing the conversion of hydrogen peroxide to free-radical ions that attack cellular membranes, proteins, and DNA. Proteins sequester iron to reduce this threat. Iron ions circulate bound to plasma transferrin and accumulate within cells in the form of ferritin.

Iron protoporphyrin (heme) and iron–sulfur clusters serve as enzyme cofactors. Under normal circumstances, only trace amounts... Figure 3 Iron Transport across the Intestinal Epithelium. Iron must cross two membranes to be transferred across the absorptive epithelium.

Each transmembrane transporter is coupled to an enzyme that changes the oxidation state of iron. The apical transporter has been identified as DMT1. It acts in concert with a type of ferrireductase activity that has not yet been cloned. The basolateral transporter has not yet been identified. This transporter requires hephaestin, a ceruloplasmin-like molecule, for the transfer of iron to the plasma. On the basis of its structure, hephaestin is presumed to be a form of ferroxidase.
