| FTL | ferritin light chain |
| target behaviour | Operant in behaviour modification therapy, the prescribed behaviour. (05 Mar 2000) |
|---|---|
| eliminative behaviour, animal | Behaviour associated with the elimination of feces and urine from the body. (12 Dec 1998) |
| type A behaviour | A behaviour pattern characterised by aggressiveness, ambitiousness, restlessness, and a strong sense of time urgency; associated with increased risk for coronary heart disease. (05 Mar 2000) |
| type B behaviour | A behaviour pattern characterised by the absence or obverse of type A behaviour characteristics. (05 Mar 2000) |
| exploratory behaviour | The tendency to explore or investigate a novel environment. It is considered a motivation not clearly distinguishable from curiosity. (12 Dec 1998) |
| feeding behaviour | Behavioural responses or sequences associated with eating including modes of feeding, rhythmic patterns of eating, and time intervals. (12 Dec 1998) |
| firesetting behaviour | A compulsion to set fires. (12 Dec 1998) |
| A chain | A polypeptide component of insulin containing 21 amino acyl residues, beginning with a glycyl residue (NH2-terminus); insulin is formed by the linkage of an A chain to a B chain by two disulfide bonds; the amino-acid composition of the A chain is a function of species. Synonym: glycyl chain. In general, one of the polypeptides in a multiprotein complex. (05 Mar 2000) |
| alpha chain disease | A vague or indefinite term; could be used for alpha-heavy-chain disease (a lymphoplasma cell proliferative disease usually seen in Mediterranean men, characterised by intestinal involvement with steatorrhoea, often progressive with fatal outcome) or a thalassaemia (a genetic abnormality in the alpha globin chain of haemoglobin). (05 Mar 2000) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
| B chain | A polypeptide component of insulin containing 30 amino acyl residues, beginning with a phenylalanyl residue (NH2-terminus); insulin is formed by the linkage of a B chain to an A chain by two disulfide bonds; the amino-acid composition of the B chain is a function of species. Synonym: phenylalanyl chain. (05 Mar 2000) |
| branched chain acyl-CoA oxidase | <enzyme> Enzyme from human liver peroxisomes acts on both 2-methyl branched fatty acyl- and bile acid-CoA intermediates, unlike rat liver peroxisomes which have separate enzymes for branched chain fatty acids (pristanoyl-CoA) and bile acid-CoA; involved in beta-oxidation of fatty acids and bil Registry number: EC 1.3.3.- Synonym: 2-methyl-branched chain acyl-CoA oxidase, hbrcacox (26 Jun 1999) |
| branched-chain fatty-acid-kinase | <enzyme> From anaerobic spirochete ma-2 Registry number: EC 2.7.2.14 Synonym: isovalerate kinase, 2-methylbutyrate kinase, isobutyrate kinase (26 Jun 1999) |
| branched-chain fatty acid synthetase | <enzyme> Analogous to fatty acid synthetase complex but starting with a branched chain keto acid; from bacillis subtilis Registry number: EC 2.3.1.- Synonym: bcfa synthetase (26 Jun 1999) |
| branched chain ketoaciduria | Hereditary disease due to deficiency of an enzyme involved in amino acid metabolism, characterised by urine that smells like maple syrup. (12 Dec 1998) |
