| 설명 | 혈액이나 소변에서 실시하는 검사항목. pH검사는 인체의 체액의 산성, 알칼리성을 알아보는 중요한 검사이다. 인체는 약알칼리성에 속하나, 이보다 pH의 증가나 감소가 나타날 경우, 생명에 위험이 발생한다. 인체내에는 이런 산도의 증감을 막기위해, 이른바 완충제들이 많이 존재하며, 특히 허파와 콩팥이 완충작용을 수행하는 주요기관이다. 콩팥은 산도가 높을 경우, 소변에서 산도를 증가시켜 배출함으로써 혈액내의 알칼리성 농도가 증가하도록 한다. 또한 허파에서도, 혈액내에 산도가 증가시 호흡을 증가함으로써 밖으로 산의 배출을 증가시킨다. 이런 허파와 콩팥의 균형은 아주 적절히 이루어지고 있으며, 어느 한 기관의 이상이 발생하면, 이런 균형은 깨어지기 쉽다. |

| 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) |

| 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) |
| hydrogen-3 | A hydrogen isotope of atomic weight 3; weakly radioactive, emitting beta particles to become the stable helium-3; half-life, 12.32 years. Synonym: tritium. (05 Mar 2000) |
| 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) |
| hydrogen bomb | <physics> An extremely powerful type of atomic bomb based on nuclear fusion. The atoms of heavy isotopes of hydrogen (deuterium and tritium) undergo fusion when subjected to the immense heat and pressure generated by the explosion of a nuclear fission unit in the bomb. (09 Oct 1997) |
| hydrogen bond | <chemistry> A weak electrostatic link between an electronegative atom (such asoxygen) and a hydrogen atom which is linked covalently to anotherelectronegative atom, hydrogen bonding is what makes water stick toitself. (09 Oct 1997) |
| hydrogen bonding | A low-energy attractive force between hydrogen and another element. It plays a major role in determining the properties of water, proteins, and other compounds. (12 Dec 1998) |
| hydrogen bromide | HBr;a colourless gas that has a very irritating odour and fumes in moist air; in aqueous solution, it is hydrobromic acid. Hydrogen chloride, HCl;a very soluble gas which, in solution, forms hydrochloric acid. (05 Mar 2000) |

| hydrogen chloride |
A toxic, colorless, strongly acidic gas (HCl) that dissolves readily in water to form hydrochloric acid. In the troposphere, hydrochloric acid can be produced from the reaction of nitric acid or sulfuric acid with sea-salt particles (NaCl). It is also involved in the formation of ammonium chloride aerosol. HCl is also the most abundant form of chlorine in an inorganic compound found in the stratosphere. ...

| hydrogen chloride |
Hydrogen chloride is a colourless gas with a pungent odour; its aqueous solution is known as hydrochloric acid. Hydrogen chloride is produced by burning hydrogen and chlorine together and is also a by-product of the chlorination of organic compounds. HCl is used in the production of PVC and silicones.
