Zinc regulation refers to the processes that control the levels of zinc in the body. Zinc is an essential trace element that plays a crucial role in various biological functions, including immune response, protein synthesis, and DNA synthesis. The body maintains zinc homeostasis through absorption in the intestines, storage in tissues, and excretion through urine and feces. The regulation of zinc involves several proteins, including metallothioneins and zinc transporters. These proteins help transport and store zinc within cells, ensuring that the body has enough for its needs while preventing toxicity from excess levels. Proper regulation is vital for overall health and well-being.
