| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| chloride depletion | Excessive loss of sodium chloride from the body in urine, sweat, etc.; a cause of secondary dehydration. Synonym: chloride depletion. Water depletion, reduction in the total volume of body water; dehydration. (05 Mar 2000) |
| chloride peroxidase | <enzyme> An enzyme that catalyses the chlorination of a range of organic molecules, forming stable carbon-chloride bonds. Chemical name: Chloride:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.10 (12 Dec 1998) |
| chloride shift | When CO2 enters the blood from the tissues, it passes into the red blood cell and is converted by carbonate dehydratase to bicarbonate (HCO3-); HCO3- ion passes out into the plasma while Cl- migrates into the red blood cell. Reverse changes occur in the lungs when CO2 is eliminated from the blood. Synonym: Hamburger's phenomenon. (05 Mar 2000) |

(05 Mar 2000) |
| methacholine chloride | <chemical> A slowly hydrolyzed muscarinic agonist. It is used as a parasympathomimetic bronchoconstrictor agent and as a diagnostic aid for bronchial asthma. It has also been used in the treatment of glaucoma and in the treatment of raynaud's syndrome and other vasospastic conditions. Pharmacological action: bronchoconstrictor agent, miotics, muscarinic agonist, parasympathomimetic. Chemical name: 1-Propanaminium, 2-(acetyloxy)-N,N,N-trimethyl- (12 Dec 1998) |
