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
