Iron storage protein ferritin

WebFerritin is the major intracellular iron storage protein in prokaryotes and eukaryotes. It is composed of 24 subunits of the heavy and light ferritin chains. Variation in ferritin subunit composition may affect the rates of iron uptake and release in different tissues. WebJan 5, 1995 · Iron Storage. Iron is stored, mostly in the liver, as ferritin or hemosiderin. Ferritin is a protein with a capacity of about 4500 iron (III) ions per protein molecule. This is the major form of iron storage. If the capacity for storage of iron in ferritin is exceeded, a complex of iron with phosphate and hydroxide forms.
