Medical term:
glycoside
glycoside
[gli´ko-sīd]any compound containing a carbohydrate molecule (sugar), particularly any such natural product in plants, convertible, by hydrolytic cleavage, into a sugar and a nonsugar component (aglycone), and named specifically for the sugar contained, such as fructoside (fructose), glucoside (glucose), or pentoside (pentose).
cardiac glycoside any of a group of glycosides occurring in certain plants (Digitalis, etc.), having a characteristic action on the contractile force of the heart muscle.

gly·co·side
(glī'kō-sīd),Condensation product of a sugar with any other radical involving the loss of the OH of the hemiacetal or hemiketal of the sugar, leaving the anomeric carbon as the link; thus, condensation through the carbon with an alcohol, which loses its hydrogen on its hydroxyl group, yields an alcohol-glycoside (or a glycosido-alcohol); links with a purine or pyrimidine -NH- group yield glycosyl (or N-glycosyl) compounds.

glycoside
BiochemistryA molecule formed from the condensation of either a furanose or a pyranose with another molecule as an acetal nitrogen glycoside or phosphate ester glycoside; cardiac glycosides include digitoxin, digoxin and ouabain.
Herbal medicine
Any of a number of medicinally active compounds produced by plants, which include hydrocyanic (prussic acid), which gives cough syrup its bitter almond flavour, digitoxin, a cardioactive agent, and salicin, the basis for salicylic acid.

gly·co·side
(glī'kō-sīd)Condensation product of a sugar with any other radical involving the loss of the H of the hemiacetal or hemiketal OH of the sugar, leaving the O of this OH as the link.

glycoside
an acetal derivative of a sugar that, on hydrolysis by enzymes or acids, gives rise to a sugar. Glycosides containing glucose are called glucosides, those with galactose are called galactosides. They render unwanted substances chemically inert or form food reserves such as GLYCOGEN.Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005
Glycoside
An herbal carbohydrate that exerts powerful effect on hormone-producing tissues. The glycoside breaks down into a sugar and a non-sugar component.
