Iron metabolism refers to the process of how the body absorbs, transports, and stores iron. Other terms that are often used to describe this concept include iron homeostasis, iron utilization, and iron regulation. Iron metabolism is important for several bodily functions, such as creating blood cells and maintaining proper oxygen levels. It is also closely linked to immune function, as the body needs iron to fight off infections. Research in this field often involves studying the various proteins and enzymes involved in iron transport and storage, as well as the mechanisms that balance iron stores. Understanding iron metabolism is crucial for identifying and treating disorders such as iron-deficiency anemia.
