Having six atoms in the molecule. [R.]

A hydrocarbon, C26H54, resembling paraffine; -- so called because each molecule has twenty-six atoms of carbon. [Written also hexacosane.]

Any member of a group of sugars containing six carbon atoms in the molecule. Some are widely distributed in nature, esp. in ripe fruits.

cts only in the presence of water, and which causes the substance acted upon to take up a molecule of water. Thus, diastase of malt, ptyalin of saliva, and boiling dilute sulphuric acid all convert starch by hydration into dextrin and sugar. Nearly all of the digestive ferments are hydrolytic in their action.…

and isolated only as a solution in water. It is regarded as a condensation product of one molecule of phosphoric acid with one of phosphorous acid, by partial dehydration.

To give inconvenience or trouble to; to disturb or molest; to discommode; to worry; to put out; as, we are incommoded by want of room.

ble greatly by numbers or by frequency of presence; to disturb; to annoy; to frequent and molest or harass; as, fleas infest dogs and cats; a sea infested with pirates. To poison vermin that infest his plants. Cowper. These, said the genius, are envy, avarice, superstition, love, with the like cares and passions that i…

The act of infesting or state of being infested; molestation; vexation; annoyance. Bacon. Free from the infestation of enemies. Donne.

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

e., having the same elements united in the same 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 molecul…

nces, which, while chemically identical (in that they have the same composition, the same molecular weights, and the same ultimate constitution), are yet physically different, as in their action on polarized light, as dextro- and lævo-tartaric acids. In such compounds there is usually at least one unsymmetrical carbon…

r stone extended into the sea to influence the current or tide, or to protect a harbor; a mole; as, the Eads system of jetties at the mouth of the Mississippi River. Jetty ad (Naut.), a projecting part at the end of a wharf; the front of a wharf whose side forms one of the cheeks of a dock.

A projection in a building; also, a pier or mole; a jetty. Shak.

and pressure, all gases and vapors contain in the same volume the same number of ultimate molecules; -- so named after Avogadro, an Italian scientist. Sometimes called Ampère's law. -- Bode's law (Astron.), an approximative empirical expression of the distances of the planets from the sun, as follows: -- Mer. Ven. Ear…

Manner of linking or of being linked; -- said of the union of atoms or radicals in the molecule.

, ect. Specific gravity 13.6. Symbol Hg (Hydrargyrum). Atomic weight 199.8. Mercury has a molecule which consists of only one atom. It was named by the alchemists after the god Mercury, and designated by his symbol, mercury.

Having the same elements united in the same proportion by weight, and with the same molecular weight, but possessing a different structure and different properties; as, methyl ether and ethyl alcohol are metameric compounds. See Isomeric.

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

The weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements; thus, an atom of oxygen weighs sixteen microcriths. See Crith. J. P. Cooke.

of matter; -- said of the properties or motions of masses, as distinguished from those of molecules or atoms. Carpenter.
