- Zinc: A mineral that is essential to the body and is a constituent of many enzymes that permit chemical reactions to proceed at normal rates. Zinc is involved in the manufacture of protein (protein synthesis) and in cell division. Zinc is also a constituent of insulin, and it is involved with the sense of smell. Food sources of zinc include meat, particularly liver and seafood; eggs; nuts; and cereal grains. Search MedTerms:

Zinc Zinc deficiency is characterized by growth retardation, loss of appetite, and impaired immune function. In more severe cases, zinc deficiency causes hair loss, diarrhea, delayed sexual maturation, impotence, hypogonadism in males, and eye and skin lesions [2,8,24,25]. Weight loss, delayed healing of wounds, taste abnormalities, and mental lethargy can also occur [5,8,26-30].

- Article Sections. Zinc is an essential micronutrient for human metabolism that catalyzes more than 100 enzymes, facilitates protein folding, and helps regulate gene expression. Patients with malnutrition, alcoholism, inflammatory bowel disease, and malabsorption syndromes are at an increased risk of zinc deficiency. Symptoms of zinc deficiency are nonspecific, including growth retardation, diarrhea, alopecia, glossitis, nail dystrophy, decreased immunity, and hypogonadism in males.

Zinc Zinc is a metal. It is called an “essential trace element” because very small amounts of zinc are necessary for human health. Zinc is used for treatment and prevention of zinc deficiency and its consequences, including stunted growth and acute diarrhea in children, and slow wound healing.It is also used for boosting the immune system, treating the common cold and recurrent ear infections, and preventing lower respiratory infections.outine zinc supplementation is not recommended without the advice of a healthcare professional. In some people, zinc might cause nausea, vomiting, diarrhea, metallic taste, kidney and stomach damage, and other side effects.

The History of Zinc The History of Zinc. Introduction. Long before the discovery of zinc as a metal, zinc ore was already being used to produce the copper-zinc alloy brass as well as zinc salts for medical purposes. Objects made of brass are known from Babylonia and Assyria from 3000 BC, and from Palestine dating from 1400 - 1000 BC.

Uses of Zinc About one-half of the zinc that is produced is used in zinc galvanizing, which is the process of adding thin layers of zinc to iron or steel to prevent rusting. third significant use of zinc is in the production of zinc oxide (the most important zinc chemical by production volume), which is used in rubber manufacturing and as a protective skin ointment. Zinc is also important for health.
