Iron chelators are compounds that bind to iron in the body, helping to remove excess iron and prevent its harmful effects. They are often used in medical treatments for conditions like hemochromatosis, where the body absorbs too much iron, leading to organ damage. By forming stable complexes with iron, these chelators facilitate its excretion through urine or feces. These agents can be synthetic or naturally occurring and are important in various fields, including medicine and agriculture. In medicine, common iron chelators include deferoxamine and deferasirox, which help manage iron overload in patients receiving frequent blood transfusions.
