Cytidine triphosphate is a pyrimidine nucleoside triphosphate.

CTP is a substrate in the synthesis of RNA.

CTP is a high-energy molecule equal to ATP, but its role in the organism is more specific than that of ATP. CTP is used as the source of energy, and as a coenzyme in metabolic reactions like the synthesis of glycerophospholipids and glycosylation of proteins.

CTP also acts as an inhibitor of the enzyme Aspartate carbamoyltransferase
