Nucleosides are glycosylamines that can be thought of as [[nucleotide]]s without a phosphate group. A nucleoside consists simply of a [[nucleobase]] (also termed a nitrogenous base) and a five-carbon sugar (either [[ribose]] or [[deoxyribose]]), whereas a [[nucleotide]] is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups. In a nucleoside, the base is bound to either ribose or deoxyribose via a beta-glycosidic linkage. Examples of nucleosides include [[cytidine]], [[uridine]], [[adenosine]], [[guanosine]], [[thymidine]] and [[inosine]].
