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 derivative of phenol or an alcohol, may also be another ...

是单糖或寡糖的半缩醛羟基与另一分子中的羟基、 氨基 或硫羟基等失水而产生 水合物。. 因此一个糖苷可分为两部分。. 一部分是糖的残基（糖去掉半缩醛羟基），另一个部分是配基（非糖部分），其键称为糖苷键。. 配基部分可以是很简单的，也可以是很复杂 ...
Glycoside - an overview | ScienceDirect Topics
Glycosides represent a large group of secondary metabolic products derived from plants, demonstrating several known functions, including growth regulation, allelopathy (inhibition of other plant growth), and defense mechanisms against damage induced by herbivores and pathogens. They are composed of two bound portions, a sugar moiety, named ...

2021年11月2日 · C -Glycosides, in which a sugar moiety is linked via a carbon-carbon (C-C) bond to a non-sugar moiety (aglycone), are found in our food and medicine. The C-C bond is cleaved by intestinal...
Glycoside - an overview | ScienceDirect Topics
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.
