| 영문 | deoxyribonucleic acid (DNA) | 한글 | 데옥시리보핵산 |
|---|---|---|---|
| 설명 | 핵산의 일종으로 DNA라고도 한다. Deoxyribonucleotide의 중합체이며 유전자의 화학적 본체이다. RNA바이러스 이외의 모든 생물은 DNA를 유전자로 지니고 있다. 디옥시리보뉴클레오티드(deoxyribonucleotide)는 염기와 당(2'-deoxy-D-ribose)과 인산으로 이루어진다. 염기는 아데닌(adenine), 구아닌(guanine), 티민(thymine)및 시토신(cytosine)의 4가지이며, 이것은 당에 부착되어 있다. 인산 역시 당의 한 부분에 부착되어 있다. 이 deoxyribonucleotide의 당은 다른 deoxy- ribonucleotide의 당과 인산을 사이에 놓고 결합을 하게 되어 하나의 긴 사슬을 형성하게 된다. 즉 당과 인산이 주축이 되어서 deoxyribonucleotide의 긴 사슬을 만든다. 이 deoxyribonucleotide의 사슬 두 개는 각각 deoxyribonucleotide에 부착되어 있는 염기들이 결합을 하여 두 개의 사슬이 결합되어 있는 이중나선 구조를 만들게 된다. 4가지 염기 아데닌은 티민과 결합을 하고, 시토신과 결합을 하게 된다. 즉 당과 인산은 긴 사슬을 만드는 역할을 하고 긴 사슬에 부착된 염기들의 결합에 의해서 두 개의 긴 사슬은 서로 붙어서 이중나선 구조를 만든다. DNA의 유전정보는 염기에 저장된다. 4개의 염기의 조합과 배열이 유전정보를 보관하는 하나의 암호 역할을 행하게 된다. |

| 영문 | ribonucleic acid | 한글 | 리보핵산 |
|---|---|---|---|
| 설명 | Ribonucleotide monomer로 이루어진 핵산으로 염기, 당, 인산으로 구성된다. 염기는 adenine, guanine, cytosine, uracil의 4종류가 있으며, 당은 5탄당이다. RNA는 DNA를 주형으로 하여 상보적으로 결합, 형성되며 단백질을 만들어내는 데에 있어 중요한 역할을 한다. 전령 RNA(mRNA)는 단백질 합성에 있어 가장 기본이 되는 DNA의 서열을 상보적으로 옮겨 받아 전달하는 전령구실을 하는 RNA. 리보솜 RNA(rRNA) 리보솜을 형성하는 4가지 RNA사슬(28S, 18S, 5.8S, 5S로 구성). 전달 RNA(tRNA) 특정 아미노산을 한쪽 끝에 지니고 상보적 서열의 mRNA와 일시적 결합을 이루며 단백질 합성에 직접 기여하는 RNA이다. |

|---|---|---|---|
| 설명 | 물에 녹았을 때 이온화하여 수소 이온을 만드는 물질. 신맛이 나고 청색 리트머스 종이를 붉게 변화시키며 염기와의 중화 반응에 의하여 물과 염을 만들고 이온화 열에서 수소보다 앞에 있는 금속과 반응하여 염을 만들면서 수소를 발생시킨다. 수소 원자를 이온화하는 힘의 강약에 따라 강산과 약산으로 나뉜다. |

| arachidonic acid | <biochemistry> An essential dietary component for mammals. The free acid is the precursor for biosynthesis of prostaglandins, thromboxanes, hydroxyeicosatetraenoic acid derivatives including leucotrienes and is thus of great biological significance. Within cells the acid is found in the esterified form as a major acyl component of membrane phospholipids (especially phosphatidyl inositol) and its release from phospholipids is thought to be the limiting step in the formation of its active metabolites.

| acid | <chemical, chemistry> A fundamental category of many compounds whose water-based solutions have a sour taste, turn blue litmus paper red and can combine with metals to form salts. They are chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. Specific types of acids include: Arrhenius acid: any chemical that increases the number of free hydrogen ions (H+) when added to a water-based solution. The more free hydrogens produced, the stronger the acid. Bronsted or Bronsted-Lowry acid: any chemical that acts as a proton donor in a chemical reaction. Lewis acid: any chemical that accepts two electrons to form a covalent bond during a chemical reaction. (13 Nov 1997) |
