| 설명 | 척추동물의 적혈구 속에 다량으로 들어있는 색소단백질. 철을 품는 포르피린 고리와 단백질의 일종(글로빈)으로 되어 있다. 철(Fe)에는 산소와 가역적으로 결합하는 능력이 있어, 생체 내에서는 산소를 운반하는 일을 한다. 혈색소 한 분자는 네 개의 폴리펩티드 사슬로 되어 있고, 각각의 폴리펩티드 사슬에는 한 개씩의 헴이 함유되어 있다. 따라서 혈색소 한 분자에는 철원자가 네 개 함유되고, 철원자 한 개에 대해 한 분자씩의 산소가 결합하므로, 혈색소 한 분자에는 산소 4분자가 결합한다. 혈색소는 산소압이 높은 허파나 아가미에서는 산소와 결합하고, 산소압이 낮은 조직에 이르면 산소를 유리한다. 더욱이 산소의 방출은 pH가 낮아짐에 따라 촉진되므로, 이산화탄소가 많고 pH가 낮은 말초조직에서는 산소를 보다 유리하기 쉽게 된다. 이산화탄소는 혈장 속에 녹아 허파에 운반되어 허파호흡으로 체외에 방출되면 pH는 다시 원상태로 돌아가고 혈색소는 다시 산소와 결합한다. 분자량 약 6,500의 색소단백질로 혈액 속에서의 함유량은 혈액 100 mL중의 그램수로 나타낸다. 정상치는 남자 16g/dL(14~18g/dL), 여자 14g/dL (12~16g/dL)이다. |

| nitric oxide | <biochemistry> This compound is produced from L arginine by the enzyme nitric oxide synthase. Acts as a potent vasorelaxant via elevation of intracellular cGMP in vascular smooth muscle. Synthesis of nitric oxide is not confined to endothelium, isoforms of nitric oxide synthase are also found in brain, neutrophils and platelets. Synonym: endothelium derived relaxation factor. Acronym: NO (29 Dec 1997) |

| nitric-oxide reductase | <enzyme> Prior to 1992 was classified as EC 1.7.99.2; a cytochrome bc complex; genbank af002217 (norb protein) and af002661 (norz protein) are from alcaligenes eutrophus Registry number: EC 1.7.99.7 Synonym: nitric oxide reductase, norb gene product, norz gene product (26 Jun 1999) |
| nitric oxide synthase | <enzyme> An enzyme that catalyses the conversion of l-arginine, NADPH, and oxygen to citrulline, nitric oxide, and NADP+. The enzyme found in brain, but not that induced in lung or liver by endotoxin, requires calcium.There are two isoforms, one constitutive and one activated by calmodulin. Chemical name: L-Arginine,NADPH:oxygen oxidoreductase (nitric-oxide-forming) Registry number: EC 1.14.13.39 Acronym: NOS (12 Dec 1998) |
| hemoglobin | <cell biology, haematology> Four subunit globular oxygen carrying protein of the erythrocytes of vertebrates and some invertebrates. It is a conjugated protein containing four haem groups and globin. There are two alpha and two beta chains (very similar to myoglobin) in adult humans, the haem moiety (an iron containing substituted porphyrin) is firmly held in a nonpolar crevice in each peptide chain. There are four globin polypeptide chains, designated alpha, beta, gamma, delta in the adult. Each is composed of several hundred amino acids. (08 Mar 2000) |
| nitric | <chemistry> Of, pertaining to, or containing, nitrogen; specifically, designating any one of those compounds in which, as contrasted with nitrous compounds, the element has a higher valence; as, nitric oxide; nitric acid. Nitric acid, a colourless or yellowish liquid obtained by distilling a nitrate with sulphuric acid. It is powerfully corrosive, being a strong acid, and in decomposition a strong oxidizer. Nitric anhydride, a white crystalline oxide of nitrogen (N2O5), called nitric pentoxide, and regarded as the anhydride of nitric acid. Nitric oxide, a colourless poisous gas (NO) obtained by treating nitric acid with copper. On contact with the air or with oxygen, it becomes reddish brown from the formation of nitric dioxide or peroxide. Origin: Cf. F. Nitrique. See Niter. Source: Websters Dictionary (01 Mar 1998) |
| nitric acid | <chemical> Nitric acid (hno3). A colourless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilisers, dye intermediates, explosives, and many different organic chemicals. Continued exposure to vapor may cause chronic bronchitis; chemical pneumonitis may occur. Chemical name: Nitric acid (12 Dec 1998) |
| nitric acid reductase | <enzyme> Found in pseudomonas stutzerie; transforms nitric oxide to nitrous oxide in an ascorbate-phenazine methosulfate-dependent reaction; not EC 1.7.99.2 Registry number: EC 1.7.99.- (26 Jun 1999) |
| acid oxide | An acid anhydride; an oxide of an electronegative element or radical; it can combine with water to form an acid. (05 Mar 2000) |
| alpha-pinene oxide lyase | <enzyme> From nocardia sp. Strain p18.3; catalyses the cleavage of both rings of the bicyclic structure with the formation of 2-methyl-5-isopropylhexa-2,5-dienal Registry number: EC 4.1.2.- Synonym: alpha-pinene oxide lyase (decyclizing) (26 Jun 1999) |

| aluminum oxide | <chemical> Aluminum oxide (al2o3). An oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc. It is used as an adsorbent, desiccating agent, and catalyst, and in the manufacture of dental cements and refractories. Chemical name: Aluminum oxide (Al2O3) (12 Dec 1998) |
