Zinc metabolism refers to the processes by which the body absorbs, utilizes, and excretes zinc, an essential trace mineral. It plays a crucial role in various biological functions, including immune response, protein synthesis, and DNA synthesis. The body primarily absorbs zinc through the intestines, where it is then transported to cells and tissues. Once inside the body, zinc is stored mainly in the muscles and bones, and it is released as needed. The kidneys help regulate zinc levels by filtering excess amounts for excretion. A balanced diet, including sources like meat, shellfish, and legumes, is vital for maintaining proper zinc metabolism.
