| 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) |
| accumulation analysis | A technique in which an intermediate of a metabolic pathway accumulates due to selective inhibition of a particular step in that pathway or in a mutant that is deficient in a certain step. The intermediate is then isolated, analyzed, and identified. (05 Mar 2000) |
| activation analysis | <radiobiology> Method for identifying and measuring chemical elements in a sample of material. Sample is first made radioactive by bombardment with neutrons, charged particles, or gamma rays. Newly formed radioactive atoms in the sample then give off characteristic radiations (such as gamma rays) that tell what kinds of atoms are present, and how many. (09 Oct 1997) |
| actuarial analysis | The application of probability and statistical methods to calculate the risk of occurrence of any event, such as onset of illness, recurrent disease, hospitalization, disability, or death. It may include calculation of the anticipated money costs of such events and of the premiums necessary to provide for payment of such costs. (12 Dec 1998) |
| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| analysis of variance | A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable. (12 Dec 1998) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| bite analysis | A study of the relations of the occlusal surfaces of opposing teeth and their effect upon related structures. Synonym: bite analysis. (05 Mar 2000) |
