| coprophile | An organism that ingests faecal material from others organisms. (05 Mar 2000) |
|---|---|
| coprophilia | 1. Attraction of microorganisms to faecal matter. 2. In psychiatry, a morbid attraction to, and interest in (with a sexual element), faecal matter. Origin: copro-+ G. Philos, fond (05 Mar 2000) |
| coprophobia | <psychology> Morbid fear of defecation and faeces. Origin: copro-+ G. Phobos, fear (05 Mar 2000) |
| coprophrasia | Involuntary utterances of vulgar or obscene words; seen in Gilles de la Tourette's syndrome. Synonym: coprophrasia. Origin: copro-+ G. Lalia, talk (05 Mar 2000) |
| coproplanesia | Rarely used term for passage of faeces through a fistula or artificial anus. Origin: copro-+ G. Planesis, a wandering (05 Mar 2000) |
| coproporphyria | Presence of coproporphyrins in the urine, as in variegate porphyria. Hereditary coproporphyria, an inherited (autosomal dominant) disorder of a deficiency of coproporphyrinogen oxidase, resulting in overproduction of porphyrin precursors leading to neurological disturbances and photosensitivity. (05 Mar 2000) |
| coproporphyrin | A test which is used to measure red blood cell porphyrin levels. Porphyrins are pigments found in both animal and plant life. This test is useful in evaluating any number of porphyrin disorders (involving the various porphyrins) of red blood cells. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Increased protoporphyrins may be seen in infection, thalassaemia, sideroblastic anaemia, iron deficient anaemia, increased erythropoiesis and lead poisoning. Increased uroporphyrins may indicate congenital erythropoietic porphyria or erythropoietic protoporphyria. (27 Sep 1997) |
| coproporphyrinogen | See: porphyrinogens. Coproporphyrinogen oxidase, an enzyme that catalyses a step in porphyrin biosynthesis, reacting coproporphyrinogen-III and O2 to form protoporphyrinogen-IX and 2CO2. A deficiency of this enzyme will result in hereditary coproporphyria. (05 Mar 2000) |
| coproporphyrinogen oxidase | <enzyme> One of the enzymes active in haem biosynthesis. It catalyses the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen III by the conversion of two propionic acid groups to two vinyl groups. It can act under both aerobic and anaerobic conditions. Chemical name: Coproporphyrinogen:oxygen oxidoreductase (decarboxylating) Registry number: EC 1.3.3.3 (12 Dec 1998) |
| coproporphyrinogens | Porphyrinogens which are intermediates in the haem biosynthesis. They have four methyl and four propionic acid side chains attached to the pyrrole rings. Coproporphyrinogens I and III are formed in the presence of uroporphyrinogen decarboxylase from the corresponding uroporphyrinogen. They can yield coproporphyrins by autooxidation or protoporphyrin by oxidative decarboxylation. (12 Dec 1998) |
| coproporphyrins | Porphyrins with four methyl and four propionic acid side chains attached to the pyrrole rings. Coproporphyrin III is excreted in the feces of persons with hereditary coproporphyria. (12 Dec 1998) |
| coprostane | The parent hydrocarbon of coprosterol. (05 Mar 2000) |
| coprostanone | 5b-Cholestan-3-one, an oxidation product of coprosterol. (05 Mar 2000) |
| coprostasis | Rarely used term for faecal impaction. Origin: copro-+ G. Stasis, a standing (05 Mar 2000) |
| coprostenol | Cholest-4-en-3b-ol;an isomer of cholesterol, differing in the position of the one double bond. Synonym: coprostenol. (05 Mar 2000) |
