glycoside(redirected from digitalis glycoside)
Also found in: Dictionary, Thesaurus, Encyclopedia.
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.

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.

Any of a group of organic compounds, occurring abundantly in plants, that yield a sugar and one or more nonsugar substances on hydrolysis.

A 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.
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.

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.
Medical Dictionary for the Health Professions and Nursing © Farlex 2012
glycosidean 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.

An herbal carbohydrate that exerts powerful effect on hormone-producing tissues. The glycoside breaks down into a sugar and a non-sugar component.
