Cytidine

Cytidine (symbol C or Cyd) is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N1-glycosidic bond. Cytidine is a component of RNA. It is a white water-soluble solid. which is only slightly soluble in ethanol.

Not to be confused with cytosine, cysteine, cystine, or cytisine.
