− | Zinc is an '''essential mineral''' and belongs to the group of nutrients called the '''trace elements'''. These are essential minerals but are designated as such because they are required in much smaller amounts than major minerals such as [[Calcium - Nutrition|calcium]] and [[Phosphorus - Nutrition|phosphorus]]. Dietary zinc exists in the divalent form (Zn<sup>2+</sup>) and is involved in '''many aspects of metabolism, mainly in enzyme-mediated reactions'''. | + | Zinc is an '''[[Nutrition Glossary#Essential Nutrients|essential]] [[Minerals - Nutrition|mineral]]''' and belongs to the group of nutrients called the '''trace elements'''.
