| 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. |

| 영문 | uric acid | 한글 | 요산 |
|---|---|---|---|
| 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. |

| 영문 | acid-fast bacillus | 한글 | 항산막대균, 항산균 |
|---|---|---|---|
| 설명 | 아닐린 색소에 염색되기 힘드나 일단 염색되면 강산으로 처리하여도 탈색되지 아니하는 세균을 통틀어 이르는 말. 결해균, 나병균 따위가 있다. |

| 영문 | acid-fast staining | 한글 | 항산염색 |
|---|---|---|---|
| 설명 | 항산성성질(좀처럼 염색이 되지 않으나 한번 염색이 되면 산성용액에 의해서 탈색이 되지 않는 성질)을 가진 균(예를 들면 결핵균 등)의 검출에 이용되는 염색방법. 방법에는 Ziehl-Neelson법과 Kinyoun법 등이 있다. |

| citric acid cycle | <biochemistry> The central feaure of oxidative metabolism. Cyclic reactions whereby acetyl CoA is oxidized to carbon dioxide providing reducing equivalents (NADH or FADH2) to power the electron transport chain. Also provides intermediates for biosynthetic processes. (16 Dec 1997) |
|---|---|
| succinic acid cycle | A series of oxidation reduction reactions in which succinic acid and other 4-carbon atoms acids (fumaric, malic, oxaloacetic) take part in the oxidation of pyruvic acid as part of the tricarboxylic acid cycle. See: dicarboxylic acid cycle. (05 Mar 2000) |
| dicarboxylic acid cycle | That portion of the tricarboxylic acid cycle involving the dicarboxylic acids (succinic, fumaric, malic, and oxaloacetic acids), a cyclic scheme in which certain steps of the tricarboxylic acid cycle are used with the glyoxylate cycle; important in the utilization of glyoxylic acid in microorganisms.

| tricarboxylic acid cycle | <biochemistry> The central feaure of oxidative metabolism. Cyclic reactions whereby acetyl CoA is oxidized to carbon dioxide providing reducing equivalents (NADH or FADH2) to power the electron transport chain. Also provides intermediates for biosynthetic processes. (16 Dec 1997) |
| fatty acid oxidation cycle | A series of reactions involving acyl-coenzyme A compounds, whereby these undergo beta oxidation and thioclastic cleavage, with the formation of acetyl-coenzyme A; the major pathway of fatty acid catabolism in living tissue. (05 Mar 2000) |
| anovulatory cycle | A sexual cycle in which no ovum is discharged. (05 Mar 2000) |
| Born-Haber cycle | <physics> This is a mathematical description of the relationship between the electron affinity, heats of atomisation, ionisation energy and lattice energy of ionic compounds. (09 Oct 1997) |
| bottoming cycle | A cogeneration system in which steam is used first for process heat and then for electric power production. (05 Dec 1998) |
| brain wave cycle | The complete upward and downward excursion of a single wave, complex, or impulse as seen on an electroencephalogram. (05 Mar 2000) |
| c3 cycle | <biochemistry> The part of the photosynthesis process where carbon dioxide is converted into three-carbon compounds, which can then be turned into six-carbon sugars. (07 Nov 1997) |
| c4 cycle | <plant biology> An alternative, very efficient pathway used by plants living in areas with low levels of carbon dioxide, to convert carbon dioxide into a form usable by the plants during photosynthesis. (09 Oct 1997) |
| Calvin Benson cycle | <biochemistry, plant biology> Metabolic pathway responsible for photosynthetic carbon dioxide fixation in plants and bacteria. The enzyme that fixes carbon dioxide is RuDP carboxylase. The cycle is the only photosynthetic pathway in C3 plants and the secondary pathway in C4 plants. The enzymes of the pathway are present in the stroma of the chloroplast. (18 Nov 1997) |
| calvin cycle | In plants, a cyclical series of carbon-fixing, sugar-producing reactions in the chloroplasts. Some of the sugars (triose phosphates) are recycled, others are stored as carbohydrates. Light is not needed for these reactions, they use the carbon dioxide and energy produced in the light reactions of photosynthesis. (09 Oct 1997) |
| carbon dioxide cycle | First, an organism which can photosynthesise (such as a plant or some bacteria) will absorb carbon dioxide (CO2) from the air and incorporate it into its body or turn it into organic matter. Then, other organisms which cannot photosynthesise will eat the organic matter, or the photosynthesising organism, and release carbon dioxide gas as a waste product back into the air. (09 Oct 1997) |
| cardiac cycle | The complete round of cardiac systole and diastole with the intervals between, or commencing with, any event in the heart's action to the moment when that same event is repeated. (05 Mar 2000) |
