| 영문 | acetic acid | 한글 | 아세트산, 초산 |
|---|---|---|---|
| 설명 | 분자식은 C2H4O2, 분자량 60.05의 저급 지방산이다. CH3COOH의 구조식을 가진 무색액체로 16.7℃에서 녹고 118.0℃에서 끓는다. 식초의 신맛을 내는 것이고, 농축된 것을 빙초산이라 한다. 상온에서는 액체이며 수용액은 약산성이다. 생체내에서는 일반적으로 아세틸 CoA로 존재하며 아세틸기의 공급원이 되는 외에 지방산이나 스테로이드 등의 생성재료로 중요하다. 아세틸 CoA로부터는 케톤체가 합성되며 조직의 에너지원이 된다. |

|---|---|---|---|
| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

| cadmium chloride | <chemical> A cadmium halide in the form of colourless crystals, soluble in water, methanol, and ethanol. It is used in photography, in dyeing, and calico printing, and as a solution to precipitate sulfides. Pharmacological action: carcinogens, mutagens, teratogens. Chemical name: Cadmium chloride (CdCl2) (12 Dec 1998) |
| caesium chloride | <chemical> Salt that yields aqueous solutions of high density. When equilibrium has been established between sedimentation and diffusion during ultracentrifugation, a linear density gradient is established in which macromolecules such as DNA band at a position corresponding to their own buoyant density. (18 Nov 1997) |
| calcium chloride | <chemical> Calcium chloride (cacl2). A salt that occurs as white, hard fragments or granules. It is used as a calcium replenisher, administered intravenously, has been used as an acid-producing diuretic and urinary acidifier and to control bleeding in such conditions as purpura, intestinal bleeding, and small multiple haemorrhages. It is also a specific antidote for magnesium poisoning, administered intravenously. Chemical name: Calcium chloride (CaCl2) (12 Dec 1998) |
| carbamylcholine chloride | A cholinomimetic drug which reacts with and activates both muscarinic and nicotinic receptors. It is slowly hydrolyzed and thus its effects far outlast those of acetylcholine. Used medically to stimulate smooth muscle, as in paralytic ileus following surgery. (05 Mar 2000) |
| magnesium chloride | <chemical> Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys. Chemical name: Magnesium chloride (MgCl2) (12 Dec 1998) |
| vinyl chloride | <chemical> A gas that has been used as an aerosol propellant and is the starting material for polyvinyl resins. Toxicity studies have shown various adverse effects, particularly the occurrence of liver neoplasms. Pharmacological action: carcinogens. Chemical name: Ethene, chloro- (12 Dec 1998) |
| cesium chloride | <chemical> Salt that yields aqueous solutions of high density. When equilibrium has been established between sedimentation and diffusion during ultracentrifugation, a linear density gradient is established in which macromolecules such as DNA band at a position corresponding to their own buoyant density.

| cesium chloride gradient centrifugation | A type of density gradient centrifugation, a lab technique used to separate or purify nucleic acids. It involves putting cesium chloride and the nucleic acids into a centrifuge to be spun for hours or days. The cesium chloride forms a density gradient (highly dense at the bottom, thinnest at the top), and the different nucleic acids separate along the gradient according to their buoyancies in different densities.
