Metabolite Identification
Common NameCytidine triphosphate
DescriptionCytidine 5'-(tetrahydrogen triphosphate) or CTP is a cytosine nucleotide containing three phosphate groups esterified to a ribose moiety at the 5' position. CTP is integral to the synthesis or mRNA, rRNA and tRNA through RNA polymerases. Cytidine triphosphate (CTP) is also critical to the synthesis of phosphatidylcholine via the enzyme CTP: phosphocholine cytidyltransferase. This reaction is the rate-limiting step in the synthesis of phosphatidylcholine.
