Haptoglobin: From hemoglobin scavenging to human health

WebSummary. Hemoglobin is the oxygen-carrying pigment present in the red blood cells. It is a tetramer having two alpha chains and two beta chains. It is considered to be made up of two dimers, each dimer including one alpha and one beta chain. One heme group is associated with each polypeptide chain. WebMethemoglobin results from oxidation of the iron moieties in hemoglobin from the ferrous (Fe 2+) to the ferric (Fe 3+) state. Normal oxygenation of hemoglobin causes a partial transfer of an electron from the iron to the bound oxygen. Iron in this state thus resembles ferric iron and the oxygen resembles superoxide (O 2 −). chisholms roslin
