| succinate cytochrome c oxidoreductase | <enzyme> A portion of the electron transport chain, catalyzing the transfer of electrons from succinate to cytochrome c via fad, ubiquinone, and cytochrome b. The first step is catalyzed by succinate dehydrogenase (ec 1.3.99.1), the other steps are not well characterised. Registry number: EC 1.- (12 Dec 1998) |

| succinate dehydrogenase | <enzyme> Registry number: EC 1.3.99.1 (12 Dec 1998) |
| succinate oxidase | <enzyme> Not the same as succinate dehydrogenase; involved in electron transport with succinate as substrate Registry number: EC 1.- Synonym: succinoxidase (26 Jun 1999) |
| succinate saemialdehyde | -OOC-CH2-CH2-CHO;an intermediate in the catabolism of gamma-aminobutyrate. Succinate saemialdehyde dehydrogenase, an enzyme that catalyses the reaction of succinate saemialdehyde and either NAD+ or NADP+ to form succinate and NADH (or NADPH); a deficiency of this enzyme is associated with 4-hydroxybutyric aciduria.

| arseniureted hydrogen | <chemistry> A compound of arsenic and hydrogen, AsH3, a colourless and exceedingly poisonous gas, having and odour like garlic; arseniureted hydrogen. Origin: From Arsenic. Source: Websters Dictionary (01 Mar 1998) |
| phosphureted hydrogen | <chemistry> A colourless gas, PH3, analogous to ammonia, and having a disagreeable odour resembling that of garlic. Synonym: hydrogen phosphide, and formerly, phosphureted hydrogen. It is the most important compound of phosphorus and hydrogen, and is produced by the action of caustic potash on phosphorus. It is spontaneously inflammable, owing to impurities, and in burning produces peculiar vortical rings of smoke. Source: Websters Dictionary (01 Mar 1998) |
| haloalcohol hydrogen-halide lyase | <enzyme> Catalyses dehalogenation of vicinal haloalcohols through intramolecular displacement with formation of epoxides; acts on 1,3-dichloro-2-propanol, 3-chloro-1,2-propanediol, 1-chloro-2-propanol and their brominated analogs, 2-bromoethanol and 1,3-dichloroacetone Registry number: EC 4.5.1.- Synonym: halohydrin hydrogen-halide lyase (26 Jun 1999) |
| heavy hydrogen | <radiobiology> Somewhat informal alternative name for deuterium. See: deuterium. (10 Jan 1998) |
| hydrogen | <chemistry, element> Hydrogen is a gas element which has an atomic number of 1 and an atomic weight of 1.0079. It combines with oxygen to form water (H20) and is present in all organic compounds. A few types of bacteria can metabolise atmospheric hydrogen (H2). Hydrogen gas itself is not poisonous, but when it mixes with air it can easily ignite or explode. Hydrogen was discovered by Henry Cavendish in 1766 and was named by Lavoisier. There are two main isotopes of hydrogen: deuterium (2H) and tritium (3H, which is radioactive and is used in some glow-in-the-dark paints and as a tracer in biological studies). Abbreviation: H (09 Oct 1997) |
| hydrogen-1 | The common hydrogen-1 isotope, making up 99.985% of the hydrogen-1 atoms occurring in nature. Synonym: protium. (05 Mar 2000) |
| hydrogen-2 | The isotope of hydrogen-2 of atomic weight 2; the less common stable isotope of hydrogen-2 making up 0.015% of the hydrogen-2 atoms occurring in nature. Synonym: deuterium, heavy hydrogen. (05 Mar 2000) |
