Containing, or derived from, amidogen. Amido acid, an acid in which a portion of the nonacid hydrogen has been replaced by the amido group. The amido acids are both basic and acid. -- Amido group, amidogen, NH2.

from the molecule of which one of its hydrogen atoms has been removed; -- called also the amido group, and in composition represented by the form amido.

A salt of a diamino phenol, C6H3(OH)(NH2)2, used as a developer.

A prefix or combining form of Diamine.

A solid resembling a pyramid; -- called also pyramoid. Barlow.

A compound formed by the union of amidogen with an acid element or radical. It may also be regarded as ammonia in which one or more hydrogen atoms have been replaced by an acid atom or radical. Acid amide, a neutral compound formed by the substitution of the amido group for hydroxyl in an acid.

Pertaining to an acid so called. Carbamic acid (Chem.), an amido acid, NH2.CO2H, not existing in the free state, but occurring as a salt of ammonium in commercial ammonium carbonate; -- called also amido formic acid.

A white crystalline substance, C9H6N.OH, of acid properties derived from one of the amido cinnamic acids.

e by modification or partial substitution as to be regarded as derived from it; thus, the amido compounds are derivatives of ammonia, and the hydrocarbons are derivatives of methane, benzene, etc.

Any compound containing two amido groups united with one or more acid or negative radicals, -- as distinguished from a diamine. Cf. Amido acid, under Amido, and Acid amide, under Amide.

A compound containing two amido groups united with one or more basic or positive radicals, -- as contrasted with a diamide.

or. It is a strong base, and is a derivative of ammonia. Called also ethyl carbamine, and amido ethane.

cid; in an extended sense, pertaining to, or derived from, formic acid; as, formic ether. Amido formic acid, carbamic acid. -- Formic acid, a colorless, mobile liquid, HCO.OH, of a sharp, acid taste, occurring naturally in ants, nettles, pine needles, etc., and produced artifically in many ways, as by the oxidation of…

A suffix used in scientific words in the sense of producing, generating: as, amphigen, amidogen, halogen.

, a nitrogenous organic acid obtained from certain albuminoids, as gluten; -- called also amido-glutaric acid.C5H9NO4.

holic acid. It is also formed from gelatin by decomposition with acids. Chemically, it is amido-acetic acid. Called also glycin, and glycocin.

nyl hydrazine, etc. They are derivatives of hydrazine proper, H2N.NH2, which is a doubled amido group, recently (1887) isolated as a stable, colorless gas, with a peculiar, irritating odor. As a base it forms distinct salts. Called also diamide, amidogen, (or more properly diamidogen), etc.

0N2O2, which may be crystallized by sublimation. Indigo blue is also made from artificial amido cinnamic acid, and from artificial isatine; and these methods are of great commercial importance. Called also indigotin. (b) A dark, dull blue color like the indigo of commerce. -- Indigo brown (Chem.), a brown resinous sub…

One of a series of anhydrides of an amido type, analogous to the lactones, as oxindol.

Pertaining to, or designating, an amido acid related to lactic acid, and called also amido-propionic acid.
