| cytidine deaminase | <enzyme> An enzyme that catalyses the deamination of cytidine, forming uridine. Chemical name: Cytidine aminohydrolase Registry number: EC 3.5.4.5 (12 Dec 1998) |
| cytidine diphosphocholine | An intermediate in the formation of phosphatidylcholine (lecithin); formed by the action of cytidine 5'-triphosphate on phosphocholine, linking the choline phosphate group to the alpha-phosphate of the cytidine 5'-triphosphate to give a pyrophosphate. Synonym: activated choline, cytidine diphosphate choline. (05 Mar 2000) |
| cytidine diphosphoglyceride | An intermediate in the formation of phospholipids (e.g., cardiolipin formed by the action on CTP and 1,2-diacylglycerols by a cytidyl transferase, releasing CDP-glyceride and pyrophosphate. (05 Mar 2000) |
| cytidine diphosphosugar | An activated form of a sugar. (05 Mar 2000) |
| cytidine monophosphate | A cytosine ribonucleotide (where the nitrogenous base cytosine is linked to the sugar ribose and a phosphate group) that helps make glycoproteins (a protein linked to a sugar or polysaccharide). (09 Oct 1997) |
| cytidine monophosphate n-acetylneuraminic acid | <chemical> A nucleoside monophosphate sugar which donates n-acetylneuraminic acid to the terminal sugar of a ganglioside or glycoprotein. Chemical name: D-glycero-beta-D-galacto-2-Nonulopyranosonic acid, 5-(acetylamino)-3,5-dideoxy-, 2-(hydrogen 5'-cytidylate) (12 Dec 1998) |

| cytidine triphosphate | A molecule which consists of the nitrogenous base cytosine linked to the sugar ribose and which has a chain of three phosphate groups attached to the ribose in a linear fashion. CTP is required for the synthesis of DNA since it is a direct precursor molecule. (09 Oct 1997) |
| adenosine 5'-diphosphate | A condensation product of adenosine with pyrophosphoric acid, formed from ATP by the hydrolysis of the terminal phosphate group of the latter compound. Acronym: ADP (05 Mar 2000) |
