Iron storage proteins are essential molecules in the body that help regulate iron levels. The two main types are ferritin and hemosiderin. Ferritin is a soluble protein that stores iron in a readily available form, while hemosiderin is an insoluble form that accumulates when there is excess iron. These proteins play a crucial role in preventing iron deficiency and toxicity. By storing iron, they ensure that the body has enough for vital processes, such as hemoglobin production in red blood cells. Proper functioning of iron storage proteins is vital for overall health and well-being.
