Abstract
Iron is required by plants, animals and microorganisms for a variety of activities, e. g. synthesizing DNA, transporting oxygen and electrons, reducing nitrogen and trapping radiant energy. To overcome the corrosive action of iron in the aerobic and saline environment of most organisms and to provide a soluble reservoir of iron, ferric ions are stored as a polynuclear complex inside a hollow protein coat made of multiple (n=24) peptide chains (subunits). The complex of iron and protein is ferritin; the protein coat is stable without the iron core and is designated apoferritin.
