vitamin    音标拼音: [v'ɑɪtəmən]
n. 维他命,维生素

维他命,维生素

vitamin
n 1: any of a group of organic substances essential in small
quantities to normal metabolism

Vitamin \Vit"a*min\ (v[imac]t"[.a]*m[i^]n), n.
any of several organic chemical substances not synthesized by
an animal and required in small quantities for normal
metabolism, present in and obtained from the natural foods
eaten by the animal. Human vitamins are also produced
synthetically, and taken in pure form or in mixtures, as
dietary supplements. Deficiencies of specific vitamins lead
to certain specific disorders, such as scurvy, caused by an
insufficiency of vitamin C (ascorbic acid).

Note: Most vitamins act as coenzymes or precursors to
coenzymes, and are not consumed for energy production
or incorporated into structural units of the cell.
[PJC]
