| coenesthesia | The general sense of bodily existence; the sensation caused by the functioning of the internal organs. Synonym: coenesthesia, sixth sense. Origin: G. Koinos, common, + aisthesis, sensation (05 Mar 2000) |
|---|---|
| coeno- | Shared in common. See: ceno-. Origin: G. Koinos, common (05 Mar 2000) |
| coenobium | <plant biology> Colony of cells formed by certain green algae, in which little or no specialisation of the cells occurs. The cells are often embedded in a mucilaginous matrix. Examples: Volvox, Pandorina. (18 Nov 1997) |
| coenocyte | <biology> Organism that is not subdivided into cells but has many nuclei within a mass of cytoplasm (a syncytium), as for example some fungi and algae and the acellular slime mould Physarum. (18 Nov 1997) |
| coenocytic | Pertaining to or having characteristics of a cenocyte. Synonym: coenocytic. (05 Mar 2000) |
| coenurosis | Cenuriasis Disease produced by the presence of a cenuris cyst that, in sheep, causes a brain infection known as "gid" for the giddy gait induced in the infected animal; human cenurosis has been reported but is extremely unusual, in contrast with hydatid disease. Synonym: coenurosis. (05 Mar 2000) |
| Coenurus | Former generic name, now used to designate larval forms of taenioid cestodes in which a bladder is formed with a number of invaginated scoleces developing within; distinguished from a hydatid cyst by the absence of free-floating daughter cyst colonies budded off within the bladder; Coenurus larvae are found in members of the genus Multiceps. Origin: G. Koinos, common, + oura, tail (05 Mar 2000) |
| Coenurus cerebralis | The coenurus larvae of the tapeworm Multiceps multiceps, found in the brain and spinal cord of sheep, goats, and other ruminants (a few have been recorded in man); adults are found in the intestine of dogs, foxes, coyotes, and jackals. (05 Mar 2000) |
| Coenurus serialis | The coenurus larvae of the tapeworm Multiceps serialis, found in subcutaneous and intramuscular tissues of rabbits and hares (a few have been recorded in man); adult worms are found in the intestine of dogs, foxes, and jackals. (05 Mar 2000) |
| coenzyme | <biochemistry> An organic nonprotein molecule, frequently a phosphorylated derivative of a water soluble vitamin, that binds with the protein molecule (apoenzyme) to form the active enzyme (holoenzyme). (18 Nov 1997) |
| coenzyme A | <biochemistry> A derivative of adenosine triphosphate and pantothenic acid that can carry acyl groups (usually acetyl) as thioesters. Involved in many metabolic pathways, for example citric acid cycle and in fatty acid oxidation. (18 Nov 1997) |
| coenzyme a ligases | <enzyme> Enzymes that catalyze the formation of acyl-CoA derivatives. Registry number: EC 6.2.1. (12 Dec 1998) |
| coenzyme a-transferases | <enzyme> Enzymes which transfer coenzyme a moieties from acyl- or acetyl-CoA to various carboxylic acceptors forming a thiol ester. Enzymes in this group are instrumental in ketone body metabolism and utilization of acetoacetate in mitochondria. Registry number: EC 2.8.3 (12 Dec 1998) |
| coenzyme B12 | <biochemistry> A coenzyme derived from cobalamine which is involved in carbon skeletal rearrangements. It is the only biomolecule known that has a carbon-metal bond. (09 Oct 1997) |
| coenzyme F | The active coenzyme form of folic acid; participates in one-carbon metabolism. Synonym: coenzyme F. (05 Mar 2000) |
