proportion by weight, but with different molecular weights; as, acetylene and benzine are isomeric (polymeric) with each other in this sense. See Polymeric. (b) Metameric; i. e., having the same elements united in the same proportions by weight, and with the same molecular weight, but which a different structure or arr…

Not isomeric; not made of the same components in the same proportions.

Any of eight isomeric liquid compounds, C5H11OH; ordinarily, a mixture of two of these forming a colorless liquid with a peculiar cough-exciting odor and burning taste, the chief constituent of fusel oil. It is used as a source of amyl compounds, such as amyl acetate, amyl nitrite, etc.

A carbohydrate, isomeric with cane sugar, contained in gum arabic, from which it is extracted as a white, amorphous substance.

A colorless liquid base, C4H9NH2, of which there are four isomeric varieties.

o a slight extent in certain animals, as the tunicates. It is a carbohydrate, (C6H10O5)n, isomeric with starch, and is convertible into starches and sugars by the action of heat and acids. When pure, it is a white amorphous mass. See Starch, Granulose, Lignin. Unsized, well bleached linen paper is merely pure cellulose…

One of the quinine group of alkaloids isomeric with and resembling cinchonidine; -- called also cinchonia.

A liquid hydrocarbon, C10H22, of the paraffin series, including several isomeric modifications.

bile, volatile liquid, C6H6, produced artificially from certain allyl derivatives. Though isomeric with benzine, it is very different in its chemical relations. Called also dipropinyl.

One of several isomeric organic bases of the quinoline series of alkaloids.

Relating to oleic acid, or elaine. Elaidic acid (Chem.), a fatty acid isomeric with oleic acid, and obtained from it by the action of nitrous acid.

A solid isomeric modification of olein.

, an acid, so called; as, fulminic acid. Fulminic acid (Chem.), a complex acid, H2C2N2O2, isomeric with cyanic and cyanuric acids, and not known in the free state, but forming a large class of highly explosive salts, the fulminates. Of these, mercuric fulminate, the most common, is used, mixed with niter, to fill percu…

ve subatance, H3C3N3O3, forming well known salts, and obtained from the fulnunates. It is isomeric with cyanuric acid, and hence is also called isocyanuric acid.

A white, crystalline sugar, C6H12O6, isomeric with dextrose, obtained by the decomposition of milk sugar, and also from certain gums. When oxidized it forms mucic acid. Called also lactose (though it is not lactose proper).

lutaric ethers. Glutaric acid, an organic acid obtained as a white crystalline substance, isomeric with pyrotartaric acid; -- called also normal pyrotartaric acid.

An isomeric variety of terpene from orange oil.

Pertaining to, or derived from, barley; as, hordeic acid, an acid identical or isomeric with lauric acid.

Pertaining to, or designating, an isomeric variety of lastic acid that breaks down into acrylic acid and water.

An alkaloid found with hyoscyamine (with which it is also isomeric) in henbane, and extracted as a white, amorphous, semisolid substance.
