Cytidine is the canonical pyrimidine RNA nucleoside, with cytosine linked to β-D-ribose. CH64010 is identified by CAS 65-46-3, molecular formula C9H13N3O5, molecular weight 243.22, and PubChem CID 6175. It is the ribose counterpart of 2'-deoxycytidine, which is cataloged separately as CH64002.

The supported research context is pyrimidine salvage and RNA nucleoside chemistry: cytidine is a uridine-cytidine kinase substrate and an unmodified pyrimidine ribonucleoside reference.

よくある質問

Is CH64010 the RNA or DNA nucleoside?

It is cytidine, the RNA (ribo) nucleoside. The DNA counterpart, 2'-deoxycytidine, is listed separately by CHEMOS.

Why is cytidine used in salvage-pathway research?

Cytidine is a substrate of uridine-cytidine kinase, the rate-limiting enzyme of pyrimidine-nucleotide salvage, so it serves as a reference substrate in salvage studies.
