Biochem/physiol Actions

Cytidine 5′-monophosphate (CMP) is used as a substrate of uridine monophosphate (UMP)/cytidine monophosphate (CMP) kinase (EC to form CDP which upon phosphorylation to CTP supports DNA and RNA biosynthesis.
The nucleoside diphosphates cytidine diphosphate (CDP) and uridine diphosphate (UDP) are essential for pyrimidine synthesis Cytidine 5′-monophosphate (CMP) nucleotide is useful in adsorption studies on biomimetic apatite for mimicking bone mineral. It also serves an immunity supplement in pediatric formulas.
