Cytidine triphosphate

Cytidine triphosphate is a pyrimidine nucleoside triphosphate. Cytidine triphosphate is a pyrimidine nucleoside triphosphate. CTP, much like ATP, consists of a ribose sugar, and three phosphate groups. The major difference between the two molecules is the base used, which in CTP is cytosine. CTP is a substrate in the synthesis of RNA. CTP is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions.CTP is a coenzyme in metabolic reactions like the synthesis of glycerophospholipids and glycosylation of proteins. CTP acts as an inhibitor of the enzyme aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis.
