Citidin je nukleozidni molekul koji je formiran dodavanjem citozina na ribozni prsten (takođe poznat kao ribofuranoza) putem β-N1-glikozidne veze. Citidin je RNK komponenta.

Citozin vezan za dezoksiribozni prsten je poznat kao dezoksicitidin.

Prehrambeni izvori citidina

[уреди | уреди извор]

Prehrambeni izvori citidina su namirnice sa visokim RNK (ribonukleinska kiselina) sadržajem,[3] poput iznutrica, pivskog kvasca, i piva. Tokom varenja, RNK-bogata hrana se razlaže u ribozil pirimidin (citidin i uridin), koje se apsorbuju nepromenjeni.[3] Kod ljudi, prehrambeni citidin se konvertuje u uridin[4].
