  • It is a component of many enzymes and is involved in protein synthesis and carbohydrate metabolism. It is crucial for cell division and elongation, which directly relate to cell growth.

  • Zinc plays an essential role in supporting the senses of smell and taste.

  • Industrially, a major portion of zinc is used for galvanizing metals like iron to protect them from rust and corrosion.
