Suck"ling (?), n. [OE. sokeling. See Suck, v. t.] 1. A young child or

Su"crose` (?), n. [F. sucre sugar. See Sugar.] (Chem.) A common variety

of sugar found in the juices of many plants, as the sugar cane,

sorghum, sugar maple, beet root, etc. It is extracted as a sweet, white

crystalline substance which is valuable as a food product, and, being

antiputrescent, is largely used in the preservation of fruit. Called

also saccharose, cane sugar, etc. By extension, any one of the class of

isomeric substances (as lactose, maltose, etc.) of which sucrose proper

is the type.

Sucrose proper is a dextrorotatory carbohydrate, C12H22O11. It does not

reduce Fehling's solution, and though not directly fermentable, yet on

standing with yeast it is changed by the diastase present to invert

sugar (dextrose and levulose), which then breaks down to alcohol and

carbon dioxide. It is also decomposed to invert sugar by heating with

acids, whence it is also called a disaccharate. Sucrose possesses at

once the properties of an alcohol and a ketone, and also forms

compounds (called sucrates) analogous to salts. Cf. Sugar.

Suc"tion (?), n. [L. sugere, suctum, to suck; cf. OF. suction. See

Suck, v. t.] The act or process of sucking; the act of drawing, as

Suction chamber, the chamber of a pump into which the suction pipe

delivers. -- Suction pipe, Suction valve, the induction pipe, and

induction valve, of a pump, respectively. -- Suction pump, the common

pump, in which the water is raised into the barrel by atmospheric

pressure. See Illust. of Pump.

||Suc*to"ri*a (?), n. pl. [NL. See Suction.] (Zoöl.) 1. An order of

||Infusoria having the body armed with somewhat stiff, tubular

||processes which they use as suckers in obtaining their food. They are

||usually stalked.
