| electron acceptor | <chemistry> A molecule or compound that gets electrons during an oxidation-reduction reaction. (19 Jan 1998) |
|---|
| acceptor | A compound that will take up a chemical group (e.g., an amine group, a methyl group, a carbamoyl group) from another compound (the donor); under the action of alanine transaminase, l-glutamic acid is an amine donor while pyruvic acid is an amine acceptor. Origin: L. Ac-cipio, pp. -ceptus, to accept (05 Mar 2000) |
|---|---|
| acceptor control | <biochemistry> The regulation of the respiration rate, governed by ADP's ability to be a phosphate group acceptor. (06 May 1997) |
| acceptor RNA | rNA |
| acceptor site | The ribosomal binding site for the aminoacyl-tRNA during protein synthesis. (05 Mar 2000) |
| acceptor splicing site | Boundary between the right end of an intron and the left end of the adjacent exon. Synonym: acceptor splicing site. (05 Mar 2000) |
| alcohol dehydrogenase (acceptor) | An oxidoreductase that reversibly converts primary alcohols to aldehydes with an H acceptor other than NADP+. (05 Mar 2000) |
| phenylglyoxylate - acceptor oxidoreductase | <enzyme> Requires coenzyme a; converts phenylglyoxylate to benzoyl-CoA with release of co2 Registry number: EC 1.2.99.- Synonym: phenylglyoxylate oxidoreductase (acylating) (26 Jun 1999) |
| proton acceptor | <chemistry> A base, an anionic substance that acceptsa proton during an acid-basereaction. (09 Oct 1997) |
| hydrogen acceptor | A molecule that, in conjunction with a tissue enzyme system, carries hydrogen from one metabolite (oxidant) to another (reductant) or to molecular oxygen to form H2O. Synonym: hydrogen acceptor. (05 Mar 2000) |
| dimethylsulfide - acceptor oxidoreductase | <enzyme> Contains b-type haem and pterin molybdenum cofactor; distinct from dimethylsulfoxide reductase; mw 152 kD; from rhodobacter sulfidophilus Registry number: EC 1.8.99.- Synonym: me2so-acceptor oxidoreductase, molybdenum oxotransferase (26 Jun 1999) |
| L-sorbose-(acceptor) 5-oxidoreductase | <enzyme> Fad-dependent enzyme that catalyses conversion of l-sorbose to l-sorbosone; 58-kD membrane protein in gluconobacter oxydans Registry number: EC 1.1.99.12 Synonym: l-sorbose dehydrogenase, sdh enzyme (26 Jun 1999) |
| aperture for electron microscopy | <technique> Anode aperture: The opening in the accelerating voltage anode shield of the electron gun through which the electrons must pass to irradiate the specimen. Condenser aperture: An opening in the condenser lens controlling the number of electrons entering the lens and the angular aperture of the electron beam. The angular aperture can also be controlled by the condenser lens current. Physical objective aperture: A metallic diaphragm, with a small central hole, used to limit the cone of electrons accepted by the objective lens. This improves image-contrast since highly scattered electrons are prevented from arriving at the Gaussian image plane and therefore cannot contribute to background fog. Aplanatic. Free from spherical aberration and coma. (05 Aug 1998) |
| Auger electron | An electron ejected from a lower energy orbital after a photoelectric interaction of an X-ray photon with a K-shell electron by the characteristic radiation photon; the Auger electron recoils with energy equal to the characteristic radiation less the difference in shell binding energies. See: photoelectric effect. (05 Mar 2000) |
| backscattered electron | <microscopy> Produced by an incident electron colliding with the nucleus of an atom in the specimen. The incident electron is then scattered backward about 180 degrees with no appreciable loss of energy, an elastic collision. (05 Aug 1998) |
| backscattered electron imaging | <microscopy> The production of backscattered electrons from a sample varies directly with the specimen's average atomic number, higher atomic number elements produce more backscattered electrons than lower atomic number ones. Detection of Backscattered Electrons is achieved by using a donut shaped solid state saemiconductor device mounted on the bottom of the objective lens. When Backscattered Electrons strike the detector electron-hole pairs are created which are then counted. This quantity is translated into a pixel intensity and displayed on the CRT, forming the image. By splitting the detector into halves (or quadrants) differences in the signal level on the individual detector segments provide surface topography information. (05 Aug 1998) |
