What role does zinc play in the body?

Zinc is a crucial trace mineral that plays several vital roles in the body, particularly in supporting the immune system, promoting wound healing, and facilitating DNA synthesis. By contributing to immune function, zinc helps maintain the integrity of the immune response, making it essential for defending the body against pathogens and infections. It also plays a significant role in the healing of wounds, as it is involved in cell division and tissue repair processes.

In terms of DNA synthesis, zinc acts as a cofactor for over 300 enzymes, many of which are involved in the synthesis and repair of DNA. Without adequate zinc, these processes can be compromised, leading to hindered cellular functions and an increased risk of illness.

Other options describe functions or roles that do not primarily correlate with zinc. Muscle growth and development, blood pressure regulation, and calcium absorption involve different nutrients and minerals, such as proteins, electrolytes, and vitamins. Therefore, identifying zinc's specific involvement in immune function, wound healing, and DNA synthesis highlights its importance in overall health.
