  Glucose \Glu"cose`\, n. [Gr. ? sweet. Cf. Glycerin.]
     [1913 Webster]
     1. A variety of sugar occurring in nature very abundantly, as
        in ripe grapes, and in honey, and produced in great
        quantities from starch, etc., by the action of heat and
        acids. It is only about half as sweet as cane sugar.
        Called also dextrose, grape sugar, diabetic sugar,
        and starch sugar. See Dextrose.
        [1913 Webster]
     2. (Chem.) Any one of a large class of sugars, isometric with
        glucose proper, and including levulose, galactose, etc.

     3. The trade name of a sirup, obtained as an uncrystallizable
        reside in the manufacture of glucose proper, and
        containing, in addition to some dextrose or glucose, also
        maltose, dextrin, etc. It is used as a cheap adulterant of
        sirups, beers, etc.

  Sugar \Sug"ar\, n. [OE. sugre, F. sucre (cf. It. zucchero, Sp.
     az['u]car), fr. Ar. sukkar, assukkar, fr. Skr. [,c]arkar[=a]
     sugar, gravel; cf. Per. shakar. Cf. Saccharine, Sucrose.]
     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.
        [1913 Webster]
     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.
           [1913 Webster]
     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.
        [1913 Webster]
     3. Compliment or flattery used to disguise or render
        acceptable something obnoxious; honeyed or soothing words.
        [1913 Webster]
     Acorn sugar. See Quercite.
     Cane sugar, sugar made from the sugar cane; sucrose, or an
        isomeric sugar. See Sucrose.

From The Collaborative International Dictionary of English v.0.48 :

  Dextrose \Dex"trose`\ (d[e^]ks"tr[=o]s`), n. [See Dexter.]
     A sirupy, or white crystalline, variety of sugar, C6H12O6
     (so called from turning the plane of polarization to the
     right), occurring in many ripe fruits, and also called
     glucose. Dextrose and levulose are obtained by the
     inversion of cane sugar or sucrose, and hence the mixture is
     called called invert sugar. Dextrose is chiefly obtained by
     the action of heat and acids on starch, and hence called also
     starch sugar. It is also formed from starchy food by the
     action of the amylolytic ferments of saliva and pancreatic
     [1913 Webster]
     Note: The solid products are known to the trade as grape
           sugar; the sirupy products as glucose, or mixing
           sirup. These are harmless, but are only about half as
           sweet as cane sugar or sucrose. Dextrously
