| cyclohexylsulfamic acid | A sweetening agent, usually used as sodium or calcium cyclamate. Synonym: cyclohexanesulfamic acid, cyclohexylsulfamic acid. (05 Mar 2000) |
| cycloid | Suggesting cyclothymia; a term applied to a person who tends to have periods of marked swings of mood, but within normal limits. Origin: cyclo-+ G. Eidos, resembling (05 Mar 2000) |
| cycloinulo-oligosaccharide fructanotransferase | <enzyme> Converts inulin into cycloinulo-oligosaccharides Registry number: EC 2.4.1.- Synonym: cioft, cftase, cycloinulooligosaccharide fructanotransferase (26 Jun 1999) |
| cycloisomaltooligosaccharide glucanotransferase | <enzyme> Catalyses the conversion of dextran to cyclic isomaltooligosaccharides by intramolecular transglucosylation (cyclization reaction); forms alpha-1,6-oligosaccharides of 7, 8 or 9 members; mw 98 kD Registry number: EC 2.4.1.- Synonym: citase (26 Jun 1999) |
| cyclol | A cyclic dipeptide postulated as occurring in proteins; it does occur in some of the ergot alkaloids. (05 Mar 2000) |
| cycloleucine | <chemical> 1-aminocyclopentanecarboxylic acid. Amino acid formed by cyclization of leucine. Has cytostatic, immunosuppressive and antineoplastic activities. Frequently encountered synonym: nsc-1026. Chemical name: Cyclopentanecarboxylic acid, 1-amino- (12 Dec 1998) |
| cyclolysin | <protein> Protein from Bordetella pertussis that is both an adenylate cyclase and a haemolysin. (18 Nov 1997) |
| cyclonamine | <chemical> 2,5-dihydroxybenzenesulfonic acid compound with diethylamine (1:1). Benzenesulfonate derivative used as a systemic haemostatic. Pharmacological action: haemostatics. Chemical name: Benzenesulfonic acid, 2,5-dihydroxy-, compd. With N-ethylethanamine (1:1) (12 Dec 1998) |
| cyclone separator | A device used to remove particulate matter suspended in exhaust gases. (05 Dec 1998) |
| cyclooxygenase | <enzyme> An enzyme protein complex present in most tissues that catalyses two steps in prostaglandin biosynthesis and produces prostaglandins and thromboxanes from arachidonic acid. The cyclooxygenase activity converts arachidonate and 2O2 to prostaglandin G2; the hydroperoxidase activity uses glutathione to convert prostaglandin G2 to prostaglandin H2. The cyclooxygenase activity is inhibited by aspirin like drugs, accounting for their anti-inflammatory effects. Synonym: prostaglandin endoperoxide synthase. (05 Mar 2000) |
