Relating to that kind of homology or symmetry, the mathematical conception of organic form, in which all axes are equal. See under Promorphology.

In promorphology, pertaining to or exhibiting that kind of organic form, in which the stereometric ground form is a pyramid, with similar poles. See Promorphology.

One of a series of artificial, organic bases, usually produced as thick viscous liquids by the action of ammonia on ethylene oxide. They have the properties both of alcohol and amines.

rm, also used adjectively, indicating hydroxyl as an ingredient. Hydroxy acid (Chem.), an organic acid, having (besides the hydroxyl group of the carboxyl radical) an alcoholic hydroxyl group, and thus having the qualities of an alcohol in addition to its acid properties; as, lactic and tartaric acids are hydroxy acids…

A nitrogenous, organic base, NH2.OH, resembling ammonia, and produced by a modified reduction of nitric acid. It is usually obtained as a volatile, unstable solution in water. It acts as a strong reducing agent.

Anterior in age to the lowest rocks which contain organic remains. Lyell.

A plant, like the fungus, which lives on dead or living organic matter. -- Hys`ter*oph"y*tal, a.

aining, or combined with, the radical NH, which is called the imido group. Imido acid, an organic acid, consisting of one or more acid radicals so united with the imido group that it contains replaceable acid hydrogen, and plays the part of an acid; as, uric acid, succinimide, etc., are imido acids.…

Quality of being inorganic. [Obs.] "The inorganity of the soul." Sir T. Browne.

guttaipercha.C5H8 -- unsaturated, and used to make synthetic rubber by polymerization. In organic chemistry, viewed conceptually as the building block of the terpene series of hydrocarbons

6O4, which is obtained as a white crystalline substance by decomposing aconitic and other organic acids.

An organic base obtained from quinoline. It is used as a febrifuge, and resembles kairine.

One of a series of organic bases obtained by the reduction of certain isonitroso compounds of the ketones. In general they are unstable oily substances having a pungent aromatic odor.

genous substances, represented by methyl ketol and related to indol. Methyl ketol, a weak organic base, obtained as a white crystalline substance having the odor of fæces.

One of a large class of organic substances resembling the aldehydes, obtained by the distillation of certain salts of organic acids and consisting of carbonyl (CO) united with two hydrocarbon radicals. In general the ketones are colorless volatile liquids having a pungent ethereal odor.

One of a series of organic compounds, regarded as anhydrides of certain hydroxy acids. In general, they are colorless liquids, having a weak aromatic odor. They are so called because the typical lactone is derived from lactic acid.

Pertaining to, or designating, an organic amido acid, which is regarded as a derivative of lactic acid and urea.

An organic residue or radical derived from lactic acid.

Pertaining to, or designating, a nitrogenous organic acid of the uric acid group, obtained by the decomposition of allantoin, and usually called allanturic acid.
