What are the roles of zinc in human body?

Human body contains a total amount of 2 to 4 g zinc. In general there is no specialized zinc storage system in human body.

Roles and functions of zinc include:
*Zinc is constituent of more than 200 metallo-enzymes, including carbonic anhydrase, alcohol dehydrogenase, superoxide dismutase, DNA-polymerase, RNA-polymerase, alkaline phosphatase and carboxy-peptidase. The zinc ion acts as a good electron acceptor, but does not participate in direct oxidation-reduction reactions. These characteristics explain the diverse biological functions of zinc in the regulation of body metabolisms.

*Zinc is required through the human body for protein synthesis, DNA synthesis, cell division, hormonal activity, neurotransmitter signaling, and other critical functions.

*Zinc has an important biochemical role in the stabilization of structure of organic components and membranes. Zinc atoms are required to stabilize the tertiary structures of the enzyme protein and to maintain the integrity of the complex enzymes molecules, but it does not impact enzyme activity.

*Zinc is an essential for the immune function and defense system of the body.

*Zinc is required for normal physiological functioning of most body systems, particularly growth and development, neurological function, and reproduction, as well as numerous catalytic, structural, and regulatory functions at the cellular level.
