Iron metabolism in the body involves several key processes: 1) Iron exists in the body bound to hemoglobin, myoglobin, enzymes, and cytochromes or stored as ferritin and hemosiderin. 2) Dietary non-heme iron is reduced and transported across the intestinal barrier by transporters before binding to transferrin in the bloodstream. 3) Transferrin transports iron through the bloodstream and delivers it to cells through endocytosis and release from endosomes. 4) Hepcidin regulates iron levels by inhibiting intestinal iron transport and macrophage recycling of iron.
