| succinylalanyl-alanyl-prolyl-phenylalanyl-7-amino-4-methylcoumarin hydrolase | <enzyme> Enzyme may be involved in attainment of transformed state Registry number: EC 3.4.24.- Synonym: suc-ala-ala-pro-phe-amc hydrolase, saapp-amc-hydrolase (26 Jun 1999) |
| essential amino acids | Alpha-amino acids nutritionally required by an organism and which must be supplied in its diet (i.e., cannot be synthesised by the organism) either as free amino acid or in proteins. (05 Mar 2000) |
| excitatory amino acids | Endogenous amino acids released by neurons as excitatory neurotransmitters. Glutamic acid is the most common excitatory neurotransmitter in the brain. Aspartic acid has been regarded as an excitatory transmitter for many years, but the extent of its role as a transmitter is unclear. (12 Dec 1998) |
| 2-amino-2-deoxy-D-galactose | <chemical> Chemical name: D-Galactose, 2-amino-2-deoxy- (12 Dec 1998) |
| 2-amino-5-phosphonovalerate | <chemical> A potent and specific antagonist of nmda receptors (receptors, nmda) in the d-enantiomeric form. The l form is inactive at nmda receptors but may affect the ap4 (2-amino-4-phosphonobutyrate; apb) excitatory amino acid receptors. Pharmacological action: excitatory amino acid antagonists. Chemical name: Norvaline, 5-phosphono- (12 Dec 1998) |
| (3-(arginyl)amino-4-(4-nitrophenyl)butyryl)-leucyl-prolyl-threonine | Pharmacological action: neurotransmitters Synonym: 2-afb(p-no2)-proctolin, (afb(p-no2)(2))-proctolin (26 Jun 1999) |
| 8-amino-7-oxononanoate synthase | <enzyme> Chemical name: 7-keto-8-aminopelargonic acid synthetase Registry number: EC 2.3.1.47 Synonym: 7-kap synthetase, 8-amino-7-oxopelargonate synthase, 7-oxo-8-aminononanoate synthase, biof gene product (26 Jun 1999) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| a1-acid glycoprotein | <biology> Plasma protein of mammals and birds, 38% carbohydrate. In humans a single chain glycoprotein of 39 kD. Increased levels are associated with inflammation, pregnancy and various diseases. (18 Nov 1997) |
| abscisic acid | <biochemistry> A lipid hormone that inhibits cell growth in plants, it is associated with fruit drop, leaf death and seed dormancy. It is synthesised in the plastids from carotenoids. This hormone helps plants deal with water loss, and its effects can be reversed with gibberellins. (06 May 1997) |
| abscisic acid 8'-hydroxylase | <enzyme> Catalyses conversion of abscisic acid to 8'-hydroxyabscisic acid, which rearranges to phaseic acid Registry number: EC 1.14.99.- Synonym: aba 8'-hydroxylase (26 Jun 1999) |
| acetic acid | <chemical> The acid most commonly associated with vinegar, it is the most commercially important organic acid and is used to manufacture a wide range of chemical products, such as plastics and Acetobacter but, except for making vinegar, is usually made through synthetic processes. Derivatives of acetic acid which may be formed by substitution reactions. Mono- and di-substituted, as well as, halogenated compounds have been synthesised. Experimentally, alpha- and n2- substituted acetic acids have been examined for their anti-inflammatory activity and effect on the central nervous system respectively. Additionally, limited exposure data has been collected on dibromo and dichloroacetic acids to determine whether they pose health effects. Synonym: ethanoic acid. (26 Jun 1999) |
| acetoacetic acid | CH3COCH2COOH;one of the ketone bodies, formed in excess and appearing in the urine in starvation or diabetes. Synonym: diacetic acid. (05 Mar 2000) |
| acetohydroxamic acid | C2H5NO2; N-Hydroxyacetamide;an inhibitor of urease, used as adjunctive therapy in chronic urea-splitting urinary infections. (05 Mar 2000) |
