|---|---|---|---|
| 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. |

| Harden-Young ester | D-fructose 1,6-bisphosphate;important intermediate in sugar metabolism. (05 Mar 2000) |
|---|---|
| Neuberg ester | <biochemistry> A phosphorylated six-carbon sugar formed in the second step of glycolysis by the action of phosphoglucose isomerase on glucose-6-phosphate. In the third step, fructose 6-phospate and ATP are used to create fructose 1,6-biphosphate, ADP and a free hydrogen with the aid of phosphofructokinase. (08 Mar 2000) |
| ng-nitroarginine methyl ester | <chemical> A non-selective inhibitor of nitric oxide synthase. It has been used experimentally to induce hypertension. Pharmacological action: enzyme inhibitors. (12 Dec 1998) |
| sugar ester | Ester of a sugar with an organic or inorganic acid; e.g., d-glucose-6-phosphate. (05 Mar 2000) |
| isoprenylcysteine methyl ester hydrolase | <enzyme> Acts on proteins post-translationally isoprenylated on a cysteine 3 amino acids in from the carboxy terminus, followed by carboxymethylation Registry number: EC 3.1.1.- Synonym: isoprenylcys methylase (26 Jun 1999) |
| thiol ester | An ester formed from a carboxylic acid and a thiol (i.e., RCO-SR') e.g., acetyl-coenzyme A. (05 Mar 2000) |
| Embden ester | Hexose phosphate;a mixture of d-glucose-6-phosphate and d-fructose 6-phosphate; significant in the understanding of sugar metabolism. (05 Mar 2000) |
| tosylarginine methyl ester | <chemical> N(2)-(p-tolylsulfonyl)-l-arginine, methyl ester. Arginine derivative which is a substrate for many proteolytic enzymes. As a substrate for the esterase from the first component of complement, it inhibits the action of c(l) on c(4). Chemical name: L-Arginine, N2-((4-methylphenyl)sulfonyl)-, methyl ester (12 Dec 1998) |
| tosylarginine methyl ester hydrolase | <enzyme> Protease from sea urchin (arbacia punctulata) eggs; fertilization in the sea urchin is accompanied by the release of this protease from eggs into the surrounding seawater; enzyme uses tame as substrate; used as a measure of trypsin-like activity; tryptase (formerly here) is mast cell tryptase (EC 3.4.21.59) Registry number: EC 3.4.- Synonym: tame hydrolase, tame esterase, esterase a2, n-tosyl-l-arginine methyl ester esterase, tamase, tamase-1 (26 Jun 1999) |
| ester | <chemistry> A general term for any organic molecule produced by combining an acid with an alcohol. A derivative of carboxylic acid (acid with a carboxyl group -COOH) which has the general formula RCOOR, where the R's stand for the same or different aliphatic groups (alkyl groups), aromatic groups (aryl groups), or hydrogen ions. (09 Oct 1997) |
| tyrosine-ester sulfotransferase | <enzyme> Also acts on phenols and organic hydroxylamines Registry number: EC 2.8.2.9 Synonym: arylsulfotransferase iv (26 Jun 1999) |
| fatty acyl ethyl ester synthase | <enzyme> Myocardial enzyme; esterifies free fatty acids in the absence of ATP and coenzyme a; the fatty acid ethyl ester synthase III has homology with glutathione s-transferase Registry number: EC 2.3.1.- Synonym: fatty acid ethyl ester synthase, fatty acid ethyl ester synthase III, faee synthase, faees-iii gene product (26 Jun 1999) |
| 7-hydroxycoumarinyl ester hyrolase | <enzyme> A recombinant cytosolic phospholipase a2 that not only possesses pla2 and lyso-pl activities, but also hydrolyzes simple fatty acid esters of 7-hydroxycoumarin Registry number: EC 3.1.1.- Synonym: 7-hcease (26 Jun 1999) |
| good cholesterol | High-density lipoprotein (HDL) cholesterol. (12 Dec 1998) |
| cholesterol | 1. <biochemistry> A pearly, fatlike steroid alcohol, C27H45OH, crystallizing in the form of leaflets or plates from dilute alcohol and found in animal fats and oils, in bile, blood, brain tissue, milk, yolk of egg, myelin sheaths of nerve fibres, the liver, kidneys and adrenal glands. It constitutes a large part of the most frequently occurring type of gallstones and occurs in atheroma of the arteries, in various cysts and in carcinomatous tissue. Most of the bodys cholesterol is synthesised in the liver, but some is absorbed from the diet. It is a precursor of bile acids and is important in the synthesis of steroid hormones. 2. <chemical> A commercial preparation of cholesterol is used as a pharmaceutic aid. Synonym: cholesterin. Origin: Gr. Stereos = solid (15 Jan 1998) |
