| Cre recombinase | <enzyme> Mediates site-specific recombination between lox p sites; member of the integrase family Registry number: EC 2.7.7.- Synonym: bacteriophage p1 recombinase cre (26 Jun 1999) |

| cream | 1. The upper fatty layer which forms in milk on standing or which is separated from it by centrifugalization; it contains about the same amount of sugar and protein as milk, but from 12 to 40% more fat. 2. Any whitish viscid fluid resembling cream. 3. A semisolid emulsion of either the oil-in-water or the water-in-oil type, ordinarily intended for topical use. Origin: L. Cremor, thick juice, broth (05 Mar 2000) |
| cream of tartar | KHC4H4O6;a diuretic and laxative. Synonym: cream of tartar, potassium acid tartrate. (05 Mar 2000) |
| crease | A line or linear depression as produced by a fold. See: fold, groove, line. (05 Mar 2000) |
| crease wound | A tangential wound that makes a furrow without perforating the skin. Synonym: crease wound, glancing wound. (05 Mar 2000) |
| creatinaemia | The presence of abnormal concentrations of creatine in peripheral blood. Origin: creatine + G. Haima, blood (05 Mar 2000) |
| creatinase | <enzyme> An enzyme catalyzing the hydrolysis of creatine to sarcosine and urea. (05 Mar 2000) |
| creatine | <biochemistry> A compound which is made by the body and is used to store energy in the form of phosphate molecules. When phosphate molecules are attached to it, it is called creatine phosphate and is capable of donating phosphate to ADP in order to make ATP. (ATP is the molecule which is converted into ADP with a release of energy that the body then uses.) (09 Oct 1997) |
| creatine kinase | <enzyme> Dimeric enzyme (82 kD) that catalyses the formation of ATP from ADP and creatine phosphate in muscle. Acronym: CK (28 May 1998) |
| creatine kinase isoenzymes | <enzyme> Three isoenzymes of creatine kinase have been identified in human tissues: mm from skeletal muscle, mb from myocardial tissue and bb from nervous tissue. Plasma from healthy humans contains mm almost exclusively. Elevated mb creatine kinase activity is a possible indicator of myocardial injury. Registry number: EC 2.7.3.- (12 Dec 1998) |
| creatine phosphate | <biochemistry> Storage compound of vertebrate muscle. See: creatine kinase. (18 Nov 1997) |
| creatine phosphokinase | <enzyme> An enzyme that is contained in skeletal muscle, smooth muscle and cardiac muscle. Creatine phosphokinase is released into the bloodstream in increased quantities if muscle in injured. Creatine phosphokinase can be fractionated so that specific measurements can be made for blood levels of creatine phosphokinase that comes exclusively from damaged heart muscle. This makes it an important test for the laboratory diagnosis of heart attack. Acronym: CPK (28 May 1998) |
| creatininase | An amidohydrolase catalyzing the conversion of creatine to creatinine. (05 Mar 2000) |
| creatinine | <biochemistry, nephrology> A waste product of protein metabolism that is found in the urine. Can be measured to assess overall kidney function. An abnormally elevated blood creatinine level is seen in those individuals with kidney insufficiency and kidney failure. (27 Sep 1997) |
| creatinine clearance | Measurement of the clearance of endogenous creatinine, used for evaluating the glomerular filtration rate (GFR). (05 Mar 2000) |
