Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [28] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [29] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [25]
