Why is zinc an essential trace element in the human body?

Zinc is an essential trace element in the human body because it serves as a vital component of numerous enzymes and plays a critical structural role in proteins.1

Its primary biological functions include:

• Enzymatic Activity: It is a key part of the enzyme carbonic anhydrase, which facilitates reactions involved in carbon dioxide metabolism. Additionally, it is a component of enzymes responsible for digesting protein within the gastrointestinal tract.2
• Gene Regulation: Zinc is essential for the regulation of gene expression.1
• Hormonal Support: Zinc found in the pancreas is believed to assist in the storage of insulin.2

Because of these roles, adequate zinc intake is necessary to avoid deficiency, which can lead to significant health issues such as impaired growth, skin lesions, slow wound healing, and reduced immune function.1
