Molecule :: Molecule (n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom..

Invertin :: Invertin (n.) An unorganized ferment which causes cane sugar to take up a molecule of water and be converted into invert sugar.

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

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..

Pentachloride :: Pentachloride (n.) A chloride having five atoms of chlorine in each molecule.

Dioxide :: Dioxide (n.) An oxide containing two atoms of oxygen in each molecule; binoxide.

Nondecane :: Nondecane (n.) A hydrocarbon of the paraffin series, a white waxy substance, C19H40; -- so called from the number of carbon atoms in the molecule..

Atomicity :: Atomicity (n.) Degree of atomic attraction; equivalence; valence; also (a later use) the number of atoms in an elementary molecule. See Valence.

Tetrylene :: Tetrylene (n.) Butylene; -- so called from the four 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..

Atom :: Atom (n.) An ultimate particle of matter not necessarily indivisible; a molecule.

Trichloride :: Trichloride (n.) A chloride having three atoms of chlorine in the molecule.

Polysulphide :: Polysulphide (n.) A sulphide having more than one atom of sulphur in the molecule; -- contrasted with monosulphide.

Pentane :: Pentane (n.) Any one of the three metameric hydrocarbons, C5H12, of the methane or paraffin series. They are colorless, volatile liquids, two of which occur in petroleum. So called because of the five carbon atoms in the molecule..

Chemistry :: Chemistry (n.) That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See Atom, Molecul

Tetradecane :: Tetradecane (n.) A light oily hydrocarbon, C14H30, of the marsh-gas series; -- so called from the fourteen carbon atoms in the molecule..

Tetrakosane :: Tetrakosane (n.) A hydrocarbon, C24H50, resembling paraffin, and like it belonging to the marsh-gas series; -- so called from having twenty-four atoms of carbon in the molecule..

Tribasic :: Tribasic (a.) Capable of neutralizing three molecules of a monacid base, or their equivalent; having three hydrogen atoms capable of replacement by basic elements on radicals; -- said of certain acids; thus, citric acid is a tribasic acid..

Quartenylic :: Quartenylic (a.) Pertaining to, or designating, an acid of the acrylic acid series, metameric with crotonic acid, and obtained as a colorless liquid; -- so called from having four carbon atoms in the molecule. Called also isocrotonic acid..

Intramolecular :: Intramolecular (a.) Between molecules; situated, or acting, between the molecules of bodies..
