Glycoside - Wikipedia
In 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.
Glycoside | Carbohydrate, Sugar & Structure | Britannica
Glycoside, any of a wide variety of naturally occurring substances in which a carbohydrate portion, consisting of one or more sugars or a uronic acid (i.e., a sugar acid), is combined with a hydroxy compound. The hydroxy compound, usually a non-sugar entity (aglycon), such as a …
Glycoside - an overview | ScienceDirect Topics
Glycosides are compounds in which a sugar molecule (glycone) is attached, through a glycosidic linkage, to the anomeric carbon of a non-sugar moiety (aglycone). Glycosides can be of several classes such as iridoid, alcoholic, anthraquinone, flavonoid, coumarin, chromone, cardiac, steviol, cyanogenic, phenolic, saponins, iridoid, thio, among others.

Glycosides are the plant secondary metabolites containing a sugar moiety that is attached with non-sugar portions. The binding between the sugar and nonsugar moiety leads to the formation of hemiacetal. It includes the alcoholic or phenolic hydroxyl group of nonsugar and aldehyde or keto group of sugar moiety.

2024年5月31日 · Glycosides are a group of organic compounds that yield one or more sugars upon hydrolysis. Structurally, a glycoside is composed of a sugar part, known as the glycone, and a non-sugar part, referred to as the aglycone or genin.

Glycosides can play several protective roles in plants. First, they can prevent infections in seeds while they lie dormant for long periods. Second, specific glycosides like triterpenoid saponins protect plants against insect pests since they decrease the survival of plant-feeding insects.
