| cytidine diphosphate diglycerides | The ester of diacylglycerol with the terminal phosphate of cytidine diphosphate. It serves as an intermediate in the biosynthesis of phosphatidylethanolamine and phosphatidylserine in bacteria. (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 phosphate | See: cytidylic acid. (05 Mar 2000) |
| 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) |
| cytidylic acid | Cytidine monophosphate (five are possible, depending on the site of attachment of the phosphate to the ribosyl OH's); a constituent of ribonucleic acids. (05 Mar 2000) |
| cytisine | A toxic selective nicotinic cholinergic alkaloid from the seed of Laburnum anagyroides and other Leguminosae. Used in pharmacological studies of nicotinic cholinergic receptors in the brain. Synonym: baptitoxine. (05 Mar 2000) |
| cyto- | Cyt- A cell. Origin: G. Kytos, a hollow (cell) (05 Mar 2000) |
| cytoanalyzer | An electronic optical machine that screens smears containing cells suspected of malignancy. Origin: cyto-+ analyzer (05 Mar 2000) |
| cytoarchitectonics | Synonym: cytoarchitecture. Origin: cyto-+ G. Architektonike, architectural (05 Mar 2000) |
| cytoarchitectural | Pertaining to cytoarchitecture. (05 Mar 2000) |
| cytoarchitecture | The specific arrangement of cells in tissue, often used to refer to the arrangement of nerve cells in the brain (cerebral cortex). (27 Sep 1997) |
