haemoglobin
haemoglobin (ˌhiːməʊˈɡləʊbɪn; ˌhɛm-) or hemoglobinn (Biochemistry) a conjugated protein, consisting of haem and the protein globin, that gives red blood cells their characteristic colour. It combines reversibly with oxygen and is thus very important in the transportation of oxygen to tissues. See also oxyhaemoglobin[C19: shortened from haematoglobulin, from haematin + globulin the two components]Thesaurus| Noun | 1. | haemoglobin - a hemoprotein composed of globin and heme that gives red blood cells their characteristic color; function primarily to transport oxygen from the lungs to the body tissues; "fish have simpler hemoglobin than mammals"Hb, hemoglobinerythrocyte, RBC, red blood cell - a mature blood cell that contains hemoglobin to carry oxygen to the bodily tissues; a biconcave disc that has no nucleushaemoprotein, hemoprotein - a conjugated protein linked to a compound of iron and porphyrinoxyhaemoglobin, oxyhemoglobin - the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs; "oxyhemoglobin transports oxygen to the cells of the body"haem, haemitin, hematin, heme, protoheme - a complex red organic pigment containing iron and other atoms to which oxygen bindsglobin, haematohiston, hematohiston - a colorless protein obtained by removing heme from hemoglobin; the oxygen carrying compound in red blood cells |

he·mo·glo·bin (Hgb, Hb) (hē'mō-glō'bin) The red respiratory protein of erythrocytes, consisting of approximately 3.8% heme and 96.2% globin, with a molecular weight of 64,450, which as oxyhemoglobin (HbO2) transports oxygen from the lungs to the tissues where the oxygen is readily released and HbO2 becomes Hb. When Hb is exposed to certain chemicals, its normal respiratory function is blocked; thus, oxygen in HbO2 is easily displaced by carbon monoxide, a process that results in the formation of fairly stable carboxyhemoglobin (HbCO), as in asphyxiation resulting from inhalation of exhaust fumes from gasoline engines. When the iron in Hb is oxidized from the ferrous to ferric state, as in poisoning with nitrates and certain other chemicals, a nonrespiratory compound, methemoglobin (MetHb), is formed.
Synonym(s): haemoglobin. haemoglobin The iron-containing protein that fills red blood cells. Haemoglobin combines readily but loosely with oxygen in conditions of high oxygen concentration, as in the lungs, and releases it when in an environment low in oxygen, as in the body tissues. In health, each 100 ml of blood contains 12–18 g of haemoglobin. The various genetically induced abnormalities of haemoglobin are called HAEMOGLOBINOPATHIES.haemoglobin a large PROTEIN molecule with a quaternary structure of four POLYPEPTIDES CHAINS, two alpha and two beta chains, each of which is complexed to a separate HAEM group. About 300 million molecules of haemoglobin occur in each red blood cell of the mammalian circulation, with each molecule binding to a maximum of four oxygen molecules, one per haem group (= oxygenation). See OXYGEN-DISSOCIATION CURVE for an explanation of oxygen carriage. Haemoglobin is found in all vertebrates and many invertebrates. In mammals the foetal haemoglobin (HbF) has a different polypeptide combination from that in postnatal ‘adult’ haemoglobin (HbA), consisting of two alpha and two gamma chains, with different oxygen-carrying characteristics (up to 30% more at low oxygen tension). An altered beta chain in HbA produces SICKLE-CELL ANAEMIA.he·mo·glo·bin (Hb) (hē'mō-glō'bin) [MIM*141800142310, MIM*141800] Red respiratory protein of erythrocytes. In humans, there are at least five kinds of normal Hb: two embryonic Hbs (Hb Gower-1, Hb Gower-2), fetal (Hb F), and two adult types (Hb A, Hb A2).
