| 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) |

| growth and embryonic development | Developmental processes from cell division to embryogenesis to postnatal growth and maturity. (12 Dec 1998) |
| primary embryonic cell | In a very young embryo, a cell still capable of differentiation. (05 Mar 2000) |
| embryonic | Undeveloped, related to the embryo. (16 Dec 1997) |
| embryonic axis | The cephalocaudal axis established in the embryo by the primitive streak. (05 Mar 2000) |
| embryonic blastoderm | That part of the blastoderm that takes part in the formation of the embryonic body. (05 Mar 2000) |
| embryonic cataract | A congenital cataract situated near the anterior Y suture of the foetal lens nucleus. (05 Mar 2000) |
| embryonic cell | One of the cells produced as the result of cell division, cleavage, in the fertilized egg. (18 Nov 1997) |
| embryonic circulation | The basic plan of the circulation of a young mammalian embryo, at first similar to that in aquatic forms, with an unpartitioned heart and conspicuous aortic arches in the branchial region; as gestation progresses, the arrangement of the major blood vessels gradually approaches that of an adult, but the routing of blood through the heart, characteristic of an adult, cannot be attained until lung breathing begins at birth. (05 Mar 2000) |
| embryonic disk | Germ disk, the point in a telolecithal ovum where the embryo begins to be formed. Synonym: embryonic disk, germinal area, area germinativa. (05 Mar 2000) |
| embryonic haemoglobin | See: haemoglobin Gower-1, haemoglobin Gower-2. (05 Mar 2000) |
| embryonic induction | The induction of differentiation in one tissue as a result of proximity to another tissue arising, for example: during gastrulation. One of the best known examples is the induction of the neural tube in the ectoderm by the underlying chordo mesoderm. Although the information to form the tube is present in the competent determined ectoderm, it must be elicited by the inducing tissue. In some cases it is known that cell cell contact between epithelium and mesenchyme is necessary. (18 Nov 1997) |
| embryonic membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| embryonic shield | A thickened area of the embryonic blastoderm from which the embryo develops. (05 Mar 2000) |
| embryonic structures | The anatomical features of the animal embryo deriving from the fertilised ovum, that eventually become the offspring. (12 Dec 1998) |
