What is the primary purpose of Zinc in the body?

Zinc plays a crucial role in protein metabolism, serving as a cofactor for numerous enzymes that facilitate the breakdown, synthesis, and modification of proteins. This mineral is essential for the proper functioning of over 300 enzymes involved in various metabolic processes, including those that help in the digestion and utilization of proteins from our diet. Furthermore, zinc contributes to the synthesis of DNA and RNA, which are vital for cell growth, repair, and division. Since protein metabolism encompasses these critical functions, the significant involvement of zinc in maintaining and regulating these processes validates its primary purpose in the body.
