What is the function of zinc in the body?

Zinc plays a crucial role in various physiological functions within the body, particularly in supporting immune function and aiding in wound healing. It is essential for the development and functioning of immune cells, such as T lymphocytes and phagocytes, which help defend the body against pathogens and infections. Additionally, zinc is involved in the synthesis of proteins and nucleic acids, processes that are vital for tissue repair and healing wounds. This mineral acts as a cofactor for numerous enzymes and is integral to maintaining the structural integrity of the immune system.

While zinc does have an indirect role in muscle growth due to its involvement in protein synthesis, its primary functions align more closely with immune support and healing processes. It is not a direct booster of energy production, nor does it specifically aid in calcium absorption in the same manner as other nutrients, such as vitamin D. Thus, the selection of the function related to immune support and wound healing is the most accurate representation of zinc's vital roles in the body.
