What is "cytidine"

n. (context biochemistry genetics English) A nucleoside consisting of cytosine linked to ribose

n. a nucleoside component of DNA; composed of cytosine and deoxyribose [syn: deoxycytidine]

Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N- glycosidic bond. Cytidine is a component of RNA.

If cytosine is attached to a deoxyribose ring, it is known as a deoxycytidine.
