| SN | sodium nitrite |
| amyl nitrite | <chemical> A vasodilator that is administered by inhalation. It is also used recreationally due to its supposed ability to induce euphoria and act as an aphrodisiac. Pharmacological action: aphrodisiacs, vasodilator agents. (12 Dec 1998) |
|---|---|
| sodium nitrite | <chemical> Nitrous acid sodium salt. Used in many industrial processes, in meat curing, colouring, and preserving, and as a reagent in analytical chemistry. It is used therapeutically as an antidote in cyanide poisoning. The compound is toxic and mutagenic and will react in vivo with secondary or tertiary amines thereby producing highly carcinogenic nitrosamines. Pharmacological action: antidotes, food preservatives, indicators and reagents, mutagens. Chemical name: Nitrous acid, sodium salt (12 Dec 1998) |
| nitrite | <chemistry> A salt of nitrous acid. Amyl nitrite, a yellow oily volatile liquid, used in medicine as a depressant and a vaso-dilator. Its inhalation produces an instantaneous flushing of the face. Origin: Cf. F. Nitrite. See Niter. Source: Websters Dictionary (01 Mar 1998) |
| nitrite dehydrogenase | <enzyme> Nitrobacter enzyme oxidises nitrite to nitrate with reduction of o2 to water by intermolecular oxygen atom transfer; not the same as nitrate reductase Registry number: EC 1.7.3.- (26 Jun 1999) |
| nitrite reductases | <enzyme> A group of enzymes that oxidise diverse nitrogenous substances to yield nitrite. Registry number: EC 1. (12 Dec 1998) |
| isobutyl nitrite | A liquid present in commercial amyl nitrite, with similar antispasmodic and vasodilator properties. (05 Mar 2000) |
| ferredoxin-nitrite oxidoreductase | <enzyme> Catalyses reduction of nitrite to ammonia with reduced ferredoxin as electron donor Registry number: EC 1.7.7.- (26 Jun 1999) |
| bacterium | <microbiology> A tiny, unicellular, prokaryotic organism that reproduces by cell division and usually has a cell wall, can be shaped like a sphere, rod or spiral and can be found in virtually any enviroment. (09 Oct 1997) |
| Binn's bacterium | A type of the typhoid-paratyphoid subgroups of the nonlactose-fermenting bacteria. (05 Mar 2000) |
| blue-green bacterium | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nitrogen fixation occur at regular intervals. According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |
| Chauveau's bacterium | Former name for Clostridium chauvoei. (05 Mar 2000) |
| pyogenic bacterium | A bacterium that causes a pyogenic infection, such as the pyogenic cocci (staphylococci, streptococci, pneumococci, meningococci) and Haemophilus influenzae. (05 Mar 2000) |
| sulphate-reducing bacterium | <microbiology> A prokaryote which is able to reduce sulphate SO4 (as a terminal electron acceptor) using electrons donated from organic acids, fatty acids, alcohols or hydrogen (electron donors). (19 Jan 1998) |
| endoteric bacterium | A bacterium that forms an endotoxin. (05 Mar 2000) |
| exoteric bacterium | A bacterium that secretes an exotoxin. (05 Mar 2000) |
| nitrite bacterium | any of the nitrobacteria that oxidize ammonia into nitrites |
