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 amine; that of two atoms, a secondary amine; that of three atoms, a tertiary amine; and that of four atoms, a quaternary ammonium ion, a positively charged ion isolated only in association with a negative ion. The amines form salts with acids.

A substance 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 amine, e.g., NH2CH3; that of two atoms, a secondary amine, e.g., NH(CH3)2; that of three atoms, a tertiary amine, 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.

amine

A class of organic compounds derived from ammonia by replacing one or more of the hydrogen atoms by a member of the paraffin series or by an aromatic group. Amines occur widely in the body, and many drugs are amines.

amine

an organic base formed by replacing one or more of the hydrogen atoms of ammonia by organic groups.

(ă-mēn') Although this word is correctly stressed on the first syllable, U.S. usage often stresses it on the last syllable as shown here.
A substance formally derived from ammonia by the replacement of one or more of the hydrogen atoms by hydrocarbon or other radicals.
