Description and Uses

Cytidine is a pyrimidine nucleoside that is composed of the pyrimidine base cytosine attached to the sugar ribose. As a constituent of RNA, cytidine pairs with guanine, and it is a precursor of uridine. Cytidine can incur several modifications in mRNA, including methylation and acetylation, that function to regulate translation. Cytidine can also be formylated to 5-formylcytidine in mitochondrial methionine transfer RNA (tRNAMet).

Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring, cytidine is a component of RNA. It was isolated from yeast nucleic acid. It can increases cell membrane phospholipids. Cytidine is used to synthesize enzyme inhibitors, antiviral agents, and anticancer agents. And also used as constituent of nucleic acids.
