Iron oxidation in hemoglobin
WebIron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to all parts of the body. Without enough iron, there aren’t enough … WebIron is distributed in six compartments in the body. i. Hemoglobin Iron is a key functional component of this oxygen transporting molecule. About 65% to 70% total body iron is found in heme group of hemoglobin. A heme group consists of iron (Fe 2+) ion held in a heterocyclic ring, known as aporphyrin. This porphyrin ring consists of four
