Cytidine is an organic base of the pyrimidine family. When cytosine combines with the sugar ribose to form a glycosidic linkage, cytosine forms its derivative cytidine. CTP is the source of the cytidine found in ribonucleic acid and deoxycytidine triphosphate is the source of the deoxycytidine in DNA. Cytidine is involved in the preservation and transfer of genetic information. Cytidine is present in every cell in the human body. Cytidine is a pyrimidine or a two ring structure that hydrogen bonds to a purine to complete a stable structure. A carbon sugar ring attaches to nitrogen in the base to form an N-glycosylic bond. The nitrogenous bases, which are primarily nonpolar, pack tightly enough to exclude water and form a stable, primarily nonpolar environment in the helix interior.
