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

Biochemistry
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.

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.

Glycoside

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

Risk factors for falls leading to major injuries: The risk factors for falls leading to major injuries in men were an absence of the quadriceps and Achilles reflexes, reduced sternal pain sense, reduced muscle strength of tibialis anterior and peroneal muscles, impaired balance and gait, a small mid-arm circumference and the use of long-acting benzodiazepines and digitalis glycosides (Table III).
Multivariate models for risk factors: The independent risk factors for injurious falls in men were the use of digitalis glycosides and gait disturbances, whereas in women the use of calcium blockers or drugs for improving peripheral circulation and short step length were independently related to injurious falls (Table IV).
Furthermore, an absence of the quadriceps reflex and the use of digitalis glycosides emerged in the model for men, and foot deformity and the use of long-acting benzodiazepines and calcium blockers in the model for women.
