Cytidine-5-triphosphate (Cytidine triphosphate, 5-CTP) disodium is a nucleoside triphosphate, that is invovled in biosynthesis of DNA, RNA and lipid. Cytidine triphosphate synthase can catalyze the formation of cytidine 5'-triphosphate from uridine 5'-triphosphate (UTP). Cytidine 5'-triphosphate disodium is an essential biomolecule in the de novo pyrimidine biosynthetic pathway in T. gondii[1].
