zinc(Zn)
(zingk)
a chemical element, atomic number 30, atomic weight 65.37. It is a trace element in the diet, a component of several enzymes,
including DNA and RNA polymerases and carbonic anhydrase. It is abundant in red meat, shellfish, liver, peas, lentils, beans,
and rice. A well-balanced diet assures adequate intake of zinc. Those who may suffer from zinc deficiency include persons
on a strictly vegetarian diet and those who are on a high-fiber diet. Severe zinc deficiency can retard growth in children,
cause a low sperm count in adult males, and retard wound healing. Excessive intake of zinc, such as in those who work with
the metal or breathe its fumes can either cause pneumoconiosis or interfere with the body's use of copper and other trace elements, producing diarrhea, nausea, vomiting, and other signs
of intestinal irritation.
