Glycosyl
Glycosyl refers to a sugar-derived substituent or moiety that is attached to another molecule through the anomeric carbon of a sugar. In most contexts, the glycosyl group is formed when a sugar residue is linked via its C-1 position, resulting in a glycosidic bond or the creation of a glycoside. The term is used as a prefix in names such as glucosyl, galactosyl, and mannosyl, to denote the presence of a sugar-derived group.
In organic synthesis, glycosyl groups are key players in the formation of glycosidic bonds. Glycosyl donors
Biologically, the term glycosyl is related to glycosylation, a post-translational modification in which sugar moieties are
