nickel

nick·el (Ni),

(nik'ĕl), Avoid the misspelling nickle.

A metallic bioelement, atomic no. 28, atomic wt. 58.6934, closely resembling cobalt and often associated with it. Protects ribosome structure against heat denaturation. A deficiency of nickel causes changes in the ultrastructure of the liver. It is a cofactor in various henzymes (for example, urease).

[abbrev. fr. Ger. kupfer-nickel, name of copper-colored ore from which nickel was first obtained; nickel, the Ger. word for a dwarfish imp]

nickel

A metallic element (atomic number 28; atomic weight 58.69) that has been linked to deficiency states in some plants and animals. In some biological systems, nickel protects against heat-induced ribosomal damage; its role in humans is uncertain, but in excess it is toxic.
