WebIn formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an O-glycoside ), N- (a glycosylamine ), S- (a thioglycoside ), or C- (a C-glycoside) glycosidic bond. According to the IUPAC, the name " C -glycoside" is a misnomer ... WebThe bond from the anomeric carbon of the first monosaccharide unit is directed downward, which is why this is known as an α-glycosidic linkage.
