Molecule :: Molecule (n.) One of the very small invisible particles of which all matter is supposed to consist.

Quartane :: Quartane (n.) Butane, each molecule of which has four carbon atoms..

Pentacid :: Pentacid (a.) Capable of neutralizing, or combining with, five molecules of a monobasic acid; having five hydrogen atoms capable of substitution by acid residues; -- said of certain complex bases..

Olein :: Olein (n.) A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0¡ C., found abundantly in both the animal and vegetable kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40¡ C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain..

Residue :: Residue (n.) That which remains of a molecule after the removal of a portion of its constituents; hence, an atom or group regarded as a portion of a molecule; -- used as nearly equivalent to radical, but in a more general sense..

Ozone :: Ozone (n.) A colorless gaseous substance (O/) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a streng oxidizer, and probably exists in the air, though by he ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine..

Pentatomic :: Pentatomic (a.) Having five atoms in the molecule.

Vacuist :: Vacuist (n.) One who holds the doctrine that the space between the bodies of the universe, or the molecules and atoms of matter., is a vacuum; -- opposed to plenist..

Molar :: Molar (a.) Of or pertaining to a mass of matter; -- said of the properties or motions of masses, as distinguished from those of molecules or atoms..

Protosulphide :: Protosulphide (n.) That one of a series of sulphides of any element which has the lowest proportion of sulphur; a sulphide with but one atom of sulphur in the molecule.

Deutoxide :: Deutoxide (n.) A compound containing in the molecule two atoms of oxygen united with some other element or radical; -- usually called dioxide, or less frequently, binoxide..

Molecularity :: Molecularity (n.) The state of consisting of molecules; the state or quality of being molecular.

Pentadecane :: Pentadecane (n.) A hydrocarbon of the paraffin series, (C15H32) found in petroleum, tar oil, etc., and obtained as a colorless liquid; -- so called from the fifteen carbon atoms in the molecule..

Palmitin :: Palmitin (n.) A solid crystallizable fat, found abundantly in animals and in vegetables. It occurs mixed with stearin and olein in the fat of animal tissues, with olein and butyrin in butter, with olein in olive oil, etc. Chemically, it is a glyceride of palmitic acid, three molecules of palmitic acid being united to one molecule of glyceryl, and hence it is technically called tripalmitin, or glyceryl tripalmitate..

Dissociation :: Dissociation (n.) The process by which a compound body breaks up into simpler constituents; -- said particularly of the action of heat on gaseous or volatile substances; as, the dissociation of the sulphur molecules; the dissociation of ammonium chloride into hydrochloric acid and ammonia..

Micella :: Micella (n.) A theoretical aggregation of molecules constituting a structural particle of protoplasm, capable of increase or diminution without change in chemical nature..

Protosilicate :: Protosilicate (n.) A silicate formed with the lowest proportion of silicic acid, or having but one atom of silicon in the molecule..

Disulphuric :: Disulphuric (a.) Applied to an acid having in each molecule two atoms of sulphur in the higher state of oxidation.

Tetrylene :: Tetrylene (n.) Butylene; -- so called from the four carbon atoms in the molecule.

Hexane :: Hexane (n.) Any one of five hydrocarbons, C6H14, of the paraffin series. They are colorless, volatile liquids, and are so called because the molecule has six carbon atoms..
