        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.

     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]

           sweet as cane sugar or sucrose. Dextrously
