A riboside is any glycoside of ribose. A glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via an O-glycosidic bond or an S-glycosidic bond (thioglycosides). When the other group is a sugar, a disaccharide rather than a glycoside results. Several sugars form an oligosaccharide, and many sugars is a polysaccharide. In a glycoside the sugar group is the glycone and the non-sugar group as the aglycone or genin part of the glycoside.
