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

(glī′kə-sīd′)
n.
Any of a group of organic compounds, occurring abundantly in plants, that yield a sugar and one or more nonsugar substances on hydrolysis.

gly′co·sid′ic (-sĭd′ĭk) adj.

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.

glycoside

Pharmacology 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, ouabain

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.

(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.

pastinaca led to the isolation and structure identification of seven flavonoid glycosides. The structures of the isolated compounds were elucidated by 1D and 2D NMR analyses, together with ESI-MS data and comparison with relevant literature data: isoquercetin (1), (21) rutin (2), (21,22) afzelin (3), (23) astragalin (4), (21,24) isorhamnetin 3-O-[beta]-glucopyranoside (5), (25) nicotiflorin (6), (21,22) and narcissoside (7).
Farmers and consumers in areas that depend upon cassava should be warned about cyanide poisoning caused by eating improperly processed or wild-cultivar cassava, and instructed to strictly adhere to the established processing methods to degrade cyanogenic glycosides.

For the purposes of the present research it was concluded that the performance, carcass weight and bone quality of broiler chickens are affected by the non-inclusion of Vitamin [D.sub.3] in the premix; although, supplemented with 50g/ton of 1,25 [(OH).sub.2][D.sub.3] glycoside. A reduction of vitamin [D.sub.3] from the premix up to 75% when the inclusion of 1,25[(OH).sub.2][D.sub.3]-glycoside maintains the performance and bone quality of the male broilers of the Cobb500[R] lineage.

The occurrence of the compound taxiphyllin, which is a cyanogenic glycoside in raw shoots and its side effect on human health claim to introduce something new way of processing using scientific input to exclude the toxic compound without disturbing the nutrient reserve.The biosynthetic precursors of the cyanogenic glycosides are different L-amino acids, which are hydroxylated, then the N-hydroxylamino acids are converted to aldoximes and these are converted into nitriles and hydroxylated to a-hydroxy nitriles and then glycosylated to cyanogenic glycosides (29).
