Human iron metabolism refers to the complex processes that regulate the uptake, storage, transport, and utilization of iron in the body. Synonyms for this term include iron homeostasis, iron balance, iron regulation, and iron metabolism regulation. These processes are essential for maintaining normal iron levels in the body, and any disruption can lead to iron deficiency or iron overload disorders. Iron metabolism plays a critical role in several biological processes, including the formation of hemoglobin, myoglobin, and other iron-containing proteins. Understanding the mechanisms of human iron metabolism is crucial for developing therapies for iron-related disorders such as anemia, hemochromatosis, and thalassemia.
