Amine

Amine
A chemical compound containing nitrogen. Amines are derived from ammonia. (The name "amine" was derived from the word "ammonia.")
* * *
A substance formally derived from ammonia by the replacement of one or more of the hydrogen atoms by hydrocarbon or other radicals. The substitution of one hydrogen atom constitutes a primary a., e.g., NH2CH3; that of two atoms, a secondary a., e.g., NH(CH3)2; that of three atoms, a tertiary a., e.g., N(CH3)3; and that of four atoms, a quaternary ammonium ion, e.g., +N(CH3)4, a positively charged ion isolated only in association with a negative ion. The amines form salts with acids.
- biogenic amines a class of compounds, each containing an a. group, produced by a living organism. This class normally does not include amino acid s.
- a. oxidase (copper-containing) an oxidoreductase containing copper, and perhaps pyridoxal phosphate, and carrying out the same reaction as a. oxidase (flavin-containing). SYN: diamine oxidase, histaminase.
- a. oxidase (flavin-containing) an oxidoreductase containing flavin and oxidizing amines with the aid of O2 and water to aldehydes or ketones with the release of NH3 and H2O2. Acted upon by antidepressants. SYN: adrenaline oxidase, diamine oxidase, monoamine oxidase, tyraminase, tyramine oxidase.
- pressor a. SYN: pressor base.
- sympathomimetic a. an agent that evokes responses similar to those produced by adrenergic nerve activity ( e.g., epinephrine, ephedrine, isoproterenol). SYN: adrenergic a., adrenomimetic a., sympathetic a..
- vasoactive a. a substance, such as histamine or serotonin, that contains amino groups and is pharmacologically characterized by its action on the blood vessel s (altering vascular caliber or permeability).

(ə-mēnґ) (amґin) an organic compound containing nitrogen; any member of a group of chemical compounds formed from ammonia by replacement of one or more of the hydrogen atoms by organic (hydrocarbon) radicals. The amines are distinguished as primary, secondary, and tertiary, according to whether one, two, or three hydrogen atoms are replaced. The amines include allylamine, arylamine, ethylamine, methylamine, phenylamine, propylamine, and many other compounds.
