Glycoside - Wikipedia
https://en.wikipedia.org/wiki/GlycosideIn chemistry, a glycoside /ˈɡlaɪkəsaɪd/ is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme

Cardiac glycoside - Wikipedia
https://en.wikipedia.org/wiki/Cardiac_glycoside- General structure
The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar (glycoside) and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence th… - Classification
Cardiac glycosides can be more specifically categorized based on the plant they are derived from, as in the following list. For example, cardenolides have been primarily derived from the foxglove plants Digitalis purpurea and Digitalis lanata, while bufadienolides have been derived from the v…

Glycoside hydrolase - Wikipedia
https://en.wikipedia.org/wiki/Glycoside_hydrolaseGlycoside hydrolases (also called glycosidases or glycosyl hydrolases) catalyze the hydrolysis of glycosidic bonds in complex sugars. They are extremely common enzymes with roles in nature including degradation of biomass such as cellulose ( cellulase ), hemicellulose, and starch ( amylase ), in anti-bacterial defense strategies (e.g., lysozyme ...
Steviol glycoside - Wikipedia
https://en.wikipedia.org/wiki/Steviol_glycosideThough there are several molecules that fall into the category of steviol glycoside, synthesis follows a similar route. Synthesis of steviol glycoside begins with isoprene units created via the DXP or MEP pathway. Two molecules derived from primary metabolism, Pyruvate and Glyceraldehyde 3-Phosphate, are the initial molecules for this pathway.
Glycoside – Wikipedia
https://de.wikipedia.org/wiki/GlycosideGlycoside, auch Glykoside, sind organische chemische Verbindungen der allgemeinen Struktur R–O–Z. Dabei ist ein Alkohol (R–OH) über eine glycosidische Bindung mit einem Zucker (Z) verbunden. Glycoside sind somit Vollacetale von Zuckern. Die Alkoholkomponente „R–O–“ kann dabei sowohl ein anderer Zucker als auch eine beliebige ...

Flavonol-3-O-glycoside glucosyltransferase - Wikipedia
https://en.wikipedia.org/wiki/Flavonol-3-O-glycoside_glucosyltransferaseIn enzymology, a flavonol-3-O-glycoside glucosyltransferase ( EC 2.4.1.240) is an enzyme that catalyzes the chemical reaction. Thus, the two substrates of this enzyme are UDP-glucose and [ [flavonol 3-O-beta-D-glucosyl- (1->2)-beta-D-glucoside]], whereas its 3 products are UDP, flavonol, and [ [3-O-beta-D-glucosyl- (1->2)-beta-D-glucosyl- (1->2 ...
