glucose
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.
