A white crystalline substance obtained by the decomposition of saponin.

act, process, or result, of soap making; conversion into soap; specifically (Chem.), the decomposition of fats and other ethereal salts by alkalies; as, the saponification of ethyl acetate.

hence (Chem.), to subject to any similar process, as that which ethereal salts undergo in decomposition; as, to saponify ethyl acetate.

A crystalline nitrogenous substance, formed in the decomposition of creatin (one of the constituents of muscle tissue). Chemically, it is methyl glycocoll.

specifically, designating an acid (C11H12O5) related to gallic acid, and obtained by the decomposition of sinapine, as a white crystalline substance.

tance, having a hot, bitter taste. When sinapine is isolated it is unstable and undergoes decomposition.

An alkaloid produced by the decomposition of solanine, as a white crystalline substance having a harsh bitter taste.

The chemical basis of sponge tissue, a nitrogenous, hornlike substance which on decomposition with sulphuric acid yields leucin and glycocoll.

An unsaturated hydrocarbon, C8H8, obtained by the distillation of storax, by the decomposition of cinnamic acid, and by the condensation of acetylene, as a fragrant, aromatic, mobile liquid; -- called also phenyl ethylene, vinyl benzene, styrol, styrene, and cinnamene.

white crystalline substance having a sweet taste and a hyacinthlike odor, obtained by the decomposition of styracin; -- properly called cinnamic, or styryl, alcohol.

ming the acid or negative constituent of sulphuric acid and the sulphates in electrolytic decomposition; -- so called in accordance with the binary theory of salts. [Written also sulphione.]

ere it is found as a component part of taurocholic acid, from which it can be prepared by decomposition of the acid. It crystallizes in colorless, regular six-sided prisms, and is especially characterized by containing both nitrogen and sulphur, being chemically amido- isethionic acid, C

present in small amount in the pancreas and spleen, and formed in large quantity from the decomposition of proteid matter by various means, -- as by pancreatic digestion, by putrefaction as of cheese, by the action of boiling acids, etc. Chemically, it consists of oxyphenol and amidopropionic acid, and by decomposition…

e. Chemically, it is composed of carbon, hydrogen, nitrogen, and oxygen, C5H4N4O3, and by decomposition yields urea, among other products. It can be made synthetically by heating together urea and glycocoll. It was formerly called also lithic acid, in allusion to its occurrence in stone, or calculus.…

y found in the urine in degeneration of the kidneys. It is readily formed by oxidation or decomposition of indican.

Indigo red, a product of the decomposition, or oxidation, of indican. It is sometimes found in the sediment of pathological urines. It is soluble in ether or alcohol, giving the solution a beautiful red color. Also called indigrubin.

H8O3 (also called pyrotritartaric acid), obtained as a white crystalline substance by the decomposition of tartaric and pyrotartaric acids.

cteristic odor of vanilla. It is extracted from vanilla pods, and is also obtained by the decomposition of coniferin, and by the oxidation of eugenol.

A liquid hydrocarbon obtained by the decomposition of veratric acid, and constituting the dimethyl ether of pyrocatechin.

An alkaloid obtained as a yellow amorphous substance by the decomposition of veratrine.
