Zinc (C0043481)

Definition (NCI) An element with atomic symbol Zn, atomic number 30, and atomic weight 65.39.
Definition (CSP) metallic trace element, atomic symbol Zn, atomic number 30; necessary in the diet, forms an essential part of many enzymes, and plays an important role in protein synthesis and in cell division.
Definition (MSH) A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
