| 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. |

| 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) |

| Gatling gun | An American machine gun, consisting of a cluster of barrels which, being revolved by a crank, are automatically loaded and fired. The improved Gatling gun can be fired at the rate of 1,200 shots per minute. Origin: From the inventor, R.J. Gatling. Source: Websters Dictionary (01 Mar 1998) |
| gun | 1. A weapon which throws or propels a missile to a distance; any firearm or instrument for throwing projectiles by the explosion of gunpowder, consisting of a tube or barrel closed at one end, in which the projectile is placed, with an explosive charge behind, which is ignited by various means. Muskets, rifles, carbines, and fowling pieces are smaller guns, for hand use, and are called small arms. Larger guns are called cannon, ordnance, fieldpieces, carronades, howitzers, etc. See these terms in the Vocabulary. "As swift as a pellet out of a gunne When fire is in the powder runne." (Chaucer) "The word gun was in use in England for an engine to cast a thing from a man long before there was any gunpowder found out." (Selden) 2. A piece of heavy ordnance; in a restricted sense, a cannon. 3. Violent blasts of wind. Guns are classified, according to their construction or manner of loading as rifled or smoothbore, breech-loading or muzzle-loading, cast or built-up guns; or according to their use, as field, mountain, prairie, seacoast, and siege guns. Armstrong gun, a wrought iron breech-loading cannon named after its English inventor, Sir William Armstrong. Great gun, a piece of heavy ordnance; hence (Fig), a person superior in any way. Gun barrel, the barrel or tube of a gun. Gun carriage, the carriage on which a gun is mounted or moved. <medicine> Gun cotton, to blow a gale. See Gun. Origin: OE. Gonne, gunne; of uncertain origin; cf. Ir, Gael) A LL. Gunna, W. Gum; possibly (like cannon) fr. L. Canna reed, tube; or abbreviated fr. OF. Mangonnel, E. Mangonel, a machine for hurling stones.

| hill | 1. A natural elevation of land, or a mass of earth rising above the common level of the surrounding land; an eminence less than a mountain. "Every mountain and hill shall be made low." (Is. Xl. 4) 2. The earth raised about the roots of a plant or cluster of plants. See Hill. 3. A single cluster or group of plants growing close together, and having the earth heaped up about them; as, a hill of corn or potatoes. Hill ant, one of numerous species of small Asiatic singing birds of the family Leiotrichidae. Many are beautifully coloured. Origin: OE. Hil, hul, AS. Hyll; akin to OD. Hille, hil, L. Collis, and prob. To E. Haulm, holm, and column. Cf. 2d Holm. To surround with earth; to heap or draw earth around or upon; as, to hill corn. "Showing them how to plant and hill it."

| Hill coefficient | A measure of cooperativity in a binding process. A Hill coefficient of 1 indicates independent binding, a value of greater than 1 shows positive cooperativity binding of one ligand facilitates binding of subsequent ligands at other sites on the multimeric receptor complex. Worked out originally for the binding of oxygen to haemoglobin (Hill coefficient of 2.8). (18 Nov 1997) |
| Hill constant | A measure of cooperativity in a binding process. A Hill coefficient of 1 indicates independent binding, a value of greater than 1 shows positive cooperativity binding of one ligand facilitates binding of subsequent ligands at other sites on the multimeric receptor complex.
