 fruit sugar 名詞

 Lev·u·lose n.  Chem. A sirupy variety of sugar, rarely obtained crystallized, occurring widely in honey, ripe fruits, etc., and hence called also fruit sugar; also called fructose.  Chemical formula: C6H12O6.  It is called levulose, because it rotates the plane of polarization of light to the left, in contrast to dextrose, the other product of the hydrolysis of sucrose. [Written also laevulose.]
 Note: ☞ It is obtained, together with an equal quantity of dextrose, by the inversion of ordinary cane or beet sugar, and hence, as being an ingredient of invert sugar, is often so called.  It is fermentable, nearly as sweet as cane sugar, and is metameric with dextrose.  Cf. Dextrose.

 Sug·ar n.
 1. A sweet white (or brownish yellow) crystalline substance, of a sandy or granular consistency, obtained by crystallizing the evaporated juice of certain plants, as the sugar cane, sorghum, beet root, sugar maple, etc. It is used for seasoning and preserving many kinds of food and drink. Ordinary sugar is essentially sucrose. See the Note below.
 Note: ☞ The term sugar includes several commercial grades, as the white or refined, granulated, loaf or lump, and the raw brown or muscovado. In a more general sense, it includes several distinct chemical compounds, as the glucoses, or grape sugars (including glucose proper, dextrose, and levulose), and the sucroses, or true sugars (as cane sugar). All sugars are carbohydrates. See Carbohydrate.
     The glucoses, or grape sugars, are ketone alcohols of the formula C6H12O6, and they turn the plane of polarization to the right or the left. They are produced from the amyloses and sucroses, as by the action of heat and acids of ferments, and are themselves decomposed by fermentation into alcohol and carbon dioxide. The only sugar (called acrose) as yet produced artificially belongs to this class. The sucroses, or cane sugars, are doubled glucose anhydrides of the formula C12H22O11. They are usually not fermentable as such (cf. Sucrose), and they act on polarized light.
 2. By extension, anything resembling sugar in taste or appearance; as, sugar of lead (lead acetate), a poisonous white crystalline substance having a sweet taste.
 3. Compliment or flattery used to disguise or render acceptable something obnoxious; honeyed or soothing words. [Colloq.]
