Deoxycytidine diphosphate

Deoxycytidine diphosphate is a nucleoside diphosphate. It is related to the common nucleic acid CTP, or cytidine triphosphate, with the -OH group on the 2' carbon on the nucleotide's pentose removed, and with one fewer phosphoryl group than CTP.
2'-Deoxycytidine diphosphate is abbreviated as dCDP.

Synthesis of cytidine nucleotides

Deoxycytidine diphosphate is synthesized through the oxidation-reduction reaction of cytidine 5'-diphosphocholine which is catalyzed by the presence of ribonucleoside-diphosphate reductase. Additionally, ribonucleoside-diphosphate reductase is capable of binding and catalyzing both the formation of deoxyribonucleotides from ribonucleotide.
