| 영문 | biosynthesis | 한글 | 생합성 |
|---|---|---|---|
| 설명 | 생물체에서 세포의 작용으로 유기물질을 합성하는 일. 생체 추출성분에 의한 생체 외에서의 반응도 이것에 포함시킨다. 효소가 그 주역이며, 생체는 외계에서 섭취한 물질을 바탕으로 많은 단계로 이루어지는 효소반응에 의하여 목적물질을 형성한다. 생리적으로는 분해대사의 반대되는 뜻을 가지며, 생체 구성물질과 그 밖의 필요성분의 합성-보급-저장에 관여한다. 일반적으로 생합성 과정은 에너지 요구성이며, 반응의 실현에는 에너지 공급반응과 함께 호흡-발효 등에 의하여 생기는 고에너지 인산결합(ATP 등)을 필요로 하는 경우가 많다. 생합성은 주로 효소반응이므로 효소반응이 가진 여러 가지 특성을 타나내고 특히 특이성이 풍부하다. 이 성질을 이용하여 실험적 또는 공업적으로도 여러 가지 물질의 선택적 합성이 가능하다. |

| 설명 | 두 개이상의 아미노산 분자 사이에서, 한쪽의 아미노기와 다른 쪽의 카르복실기가 물 분자를 잃으면서 축합하여 이루는 아미드 결합아미노산의 수가 2, 3, … 인 경우, 각각 디펩티드, 트리펩티드, …등으로 부르며, 여러 개의 아미노산으로 구성되는 것을 올리고펩티드, 이보다 큰 것을 폴리펩티드라고 한다. 직쇄상의 것이 많지만, 환상 구조를 갖는 펩티드도 있다. 저분자의 펩티드는 물, 산, 알칼리 따위에 잘 녹고 알코올에는 녹지 않으나, 고분자의 펩티드는 물에 잘 녹지 않고 단백질과 성질이 비슷하다. 뇌하수체호르몬, 브라디키닌 등과 같이 생리적기능이 현저한 것은 생리활성펩티드(bioactive peptide)라고 한다. |

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

| biosynthesis | <biochemistry> The building up of a chemical compound in the physiologic processes of a living organism. (18 Nov 1997) |
|---|---|
| regulatory sequences, nucleic acid | DNA sequences involved in regulating the expression of other genes. (12 Dec 1998) |
| repetitive sequences, nucleic acid | Nucleotide sequences present in multiple copies in the genome. They include direct, inverted, tandem, and terminal repeat sequences and the alu family repeat (named for the restriction endonuclease cleavage enzyme alu I). (12 Dec 1998) |
| minus-strand nucleic acid | <molecular biology> An RNA or DNA strand which has the opposite sense of (would be complementary to) the mRNA of a virus. (12 Jan 1998) |
| sequence homology, nucleic acid | The sequential correspondence of nucleotide triplets in a nucleic acid molecule which permits nucleic acid hybridization. Sequence homology is important in the study of mechanisms of oncogenesis and also as an indication of the evolutionary relatedness of different organisms. The concept includes viral homology. (12 Dec 1998) |
| nucleic acid | <biochemistry, molecular biology> Linear polymers of nucleotides, linked by 3', 5' phosphodiester linkages. In DNA, deoxyribonucleic acid, the sugar group is deoxyribose and the bases of the nucleotides adenine, guanine, thymine and cytosine. RNA, ribonucleic acid, has ribose as the sugar and uracil replaces thymine. DNA functions as a stable repository of genetic information in the form of base sequence. RNA has a similar function in some viruses but more usually serves as an informational intermediate (mRNA), a transporter of amino acids (tRNA), in a structural capacity or, in some newly discovered instances, as an enzyme. The spontaneous loss of the amino groups of cytosine (yielding uracil), methyl cytosine (yielding thymine) or of adenine (yielding hypoxanthine). It can be argued that the presence of thymine in DNA in place of the uracil of RNA stabilises genetic information against this lesion, since repair enzymes would restore the GU base pair to GC. (18 Nov 1997) |
| nucleic acid base | A purine or pyrimidine; found in naturally occurring nucleic acids such as DNA. (05 Mar 2000) |
| nucleic acid conformation | The characteristic 3-dimensional shape of a nucleic acid or polynucleotide. Its secondary structure is due to the formation of hydrogen bonds between nucleotides, resulting in base pairing and areas with alpha helix structure. (12 Dec 1998) |
| nucleic acid denaturation | Disorganization of secondary structures of nucleic acids through cleavage of hydrogen bonds and hydrophobic linkages. Denatured DNA appears to be a single-stranded flexible structure. The effects of denaturation on RNA are similar though less pronounced and largely reversible. (12 Dec 1998) |
| nucleic acid heteroduplexes | Double-stranded nucleic acid molecules (DNA-DNA or DNA-RNA) which contain regions of nucleotide mismatches (non-complementary). In vivo, these heteroduplexes can result from mutation or genetic recombination; in vitro, they are formed by nucleic acid hybridization. Electron microscopic analysis of the resulting heteroduplexes facilitates the mapping of regions of base sequence homology of nucleic acids. (12 Dec 1998) |
| nucleic acid hybridization | Widely used technique which exploits the ability of complementary sequences in single-stranded dnas or rnas to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands. (kendrew, encyclopedia of molecular biology, 1994, p503; dorlands, 28th ed, p781) (12 Dec 1998) |
| nucleic acid precursors | Use for nucleic acid precursors in general or for which there is no specific heading. (12 Dec 1998) |
| nucleic acid probe | A nucleic acid fragment, labelled by a radioisotope, biotin, etc., that is complementary to a sequence in another nucleic acid (fragment) and that will, by hydrogen binding to the latter, locate or identify it and be detected; a diagnostic technique based on the fact that every species of microbe possesses some unique nucleic acid sequences which differentiate it from all others, and thus can be used as identifying markers or "fingerprints." (05 Mar 2000) |
| nucleic acid probes | Nucleic acid which complements a specific mRNA or DNA molecule, or fragment thereof; used for hybridization studies in order to identify microorganisms and for genetic studies. (12 Dec 1998) |
| nucleic acid renaturation | The reformation of all, or part of, the native conformation of a nucleic acid molecule after the molecule has undergone denaturation. (12 Dec 1998) |
