Iron Homeostasis

Meaning

Iron Homeostasis is the exquisitely tightly regulated biological process dedicated to maintaining stable and appropriate levels of iron within the body, a balance necessary to ensure sufficient iron for critical physiological functions while simultaneously preventing its potentially toxic accumulation. Iron is absolutely indispensable for fundamental processes like oxygen transport, DNA synthesis, and cellular respiration, yet an excess of unbound free iron can catalyze the generation of highly damaging reactive oxygen species. This critical balance is meticulously managed through the coordinated control of absorption, internal storage, and systemic recycling.
