{ } a. [ L. dextrorsum, contr. fr. dextrovorsum, dextroversum, toward the right side; dexter right + versus, vorsus, p. p. of vertere, vortere, to turn. ] (Botany) Turning from the left to the right, in the ascending line, as in the spiral inclination of the stem of the common morning-glory; as, dextrorse vines. [ 1913 Webster ]

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 ]

☞ 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.

a., adv., n. Same as Dexterous, Dexterously, etc. [ 1913 Webster ]
