     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.

  Dextrose \Dex"trose`\ (d[e^]ks"tr[=o]s`), n. [See {Dexter}.]
     (Chem.)
     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
     juice.
     [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
           Dextrous
