| 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) |

| angina, unstable | Precordial pain at rest, which may precede a myocardial infarction. (12 Dec 1998) |
| DNA sequence, unstable | DNA region comprised of a variable number of repetitive, contiguous trinucleotide sequences. Presence of these regions is associated with diseases such as fragile x syndrome and myotonia atrophica. (12 Dec 1998) |
| unstable angina | <cardiology> Angina which is new onset or prior existing angina which is increasing in severity, duration or frequency. (13 Nov 1997) |
| unstable bladder | Characterised by uninhibited detrusor contractions. (05 Mar 2000) |
| unstable cervical spine fractures | <radiology> Flexion: bilateral interfacetal dislocation, flexion teardrop fracture (usually C5 or C6) extension: extension teardrop fracture (usually C2 or C3), hangman's fracture, extension-dislocation, extension-fracture-dislocation, odontoid fracture vertical compression: Jefferson burst fracture see: cervical spine fractures (12 Dec 1998) |
| unstable colloid | A colloid that is not again soluble in water after having been dried at ordinary temperature. Synonym: unstable colloid. (05 Mar 2000) |
| unstable fracture | A fracture with an intrinsic tendency to slip out of place after reduction. (05 Mar 2000) |
| unstable haemoglobin haemolytic anaemia | A congenital haemolytic anaemia, due to autosomal inheritance of one of many unstable haemoglobins. The anaemia is of variable severity and characterised by the presence in vivo or in vitro of Heinz bodies. (05 Mar 2000) |
| unstable haemoglobins | A group of rare Hb's with amino acid substitutions (or amino acid deletions in three types) that alter the three-dimensional shape of the globin in a manner that renders the molecule unstable; they have an increased but variable tendency to auto-oxidation and Heinz body formation and are associated with congenital nonspherocytic haemolytic anaemia. The unstable b chain abnormalities include Hb's Genova, Gun Hill, Hammersmith, Koln, Philly, Sabine, Santa Ana, Sydney, Wien, and Zurich; unstable a chain abnormalities include Hb's Bibba, Sinai, and Torino. (05 Mar 2000) |
| unstable mutation | <molecular biology> A mutation that has a high likelihood of reverting to its original form. (13 Nov 1997) |
| unstable patient | The distinction of stability is made by a physician and based on a large number of variables: patient diagnosis, vital signs, physical findings, laboratory findings, subjective factors and patient prognosis. (27 Sep 1997) |
