Copper metabolism refers to the process by which the body absorbs, utilizes, and excretes copper, an essential trace mineral. Copper is vital for various bodily functions, including the formation of red blood cells, maintaining healthy bones, and supporting the immune system. It is primarily absorbed in the small intestine and transported to the liver, where it is stored and distributed to other tissues. The body regulates copper levels through a balance of absorption and excretion. Excess copper is eliminated through bile, while deficiencies can lead to health issues such as Wilson's disease or Menkes syndrome. Proper copper metabolism is crucial for overall health and well-being.
