| standard error of the mean | A statistical index of the probability that a given sample mean is representative of the mean of the population from which the sample was drawn. (05 Mar 2000) |
| law of regression to mean | In a population mating at random, the progeny of a parent with an extreme value for a measurable phenotype will tend on average to have values nearer the population mean than in the extreme parent. See: law of regression to mean. Synonym: law of regression to mean. (05 Mar 2000) |
| aberrant haemoglobin | A mutant Hb that functions abnormally. Compare: variant haemoglobin. (05 Mar 2000) |
| bile pigment haemoglobin | <protein> A protein which is formed from the breakdown of haemoglobin (a protein that carries oxygen in the blood) and is a precursor to the bile pigment biliverdin. (09 Oct 1997) |
| carbon monoxide haemoglobin | <chemical> Chemical name: Haemoglobins, carbonyl- (12 Dec 1998) |
| variant haemoglobin | A harmless mutant form of Hb. (05 Mar 2000) |
| reduced haemoglobin | The form of Hb in red blood cells after the oxygen of oxyhemoglobin is released in the tissues. (05 Mar 2000) |
| glycosylated haemoglobin | <biochemistry> A test which measures the amount of glucose-bound haemoglobin. As the blood glucose level increases the proportion of haemoglobin molecules which bind glucose increases with time. The measurement of glycosylated haemoglobin yields important information regarding how well a patients diabetes is being controlled. (27 Sep 1997) |
| glycosylated haemoglobin test | <investigation> A blood test that measures a person's average blood glucose (sugar) level for the 2- to 3-month period before the test. See: haemoglobin A1C. (09 Oct 1997) |
| green haemoglobin | <protein> A protein which is formed from the breakdown of haemoglobin (a protein that carries oxygen in the blood) and is a precursor to the bile pigment biliverdin. (09 Oct 1997) |
| muscle haemoglobin | <physiology> Protein (17.5 kD) found in red skeletal muscle. It was the first protein for which the tertiary structure was determined by X-ray diffraction, by J.C.Kendrew's group working on sperm whale myoglobin. It is a single polypeptide chain of 153 amino acids, containing a haem group bonded via its ferric iron to two histidine residues. It binds oxygen noncooperatively and has a higher affinity for oxygen than haemoglobin at all partial pressures. In capillaries oxygen is effectively removed from haemoglobin and diffuses into muscle fibres where it binds to myoglobin which acts as an oxygen store. (18 Nov 1997) |
| haemoglobin | <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) |
| haemoglobin A | <haematology> Haemoglobin A is the normal form of the protein haemoglobin which is found in adults. It is composed of two alpha chains and two beta chains. (09 Oct 1997) |
| haemoglobin A1C | <haematology> The substance of red blood cells that carries oxygen to the cells and sometimes joins with glucose. Because the glucose stays attached for the life of the cell (about 4 months), a test to measure haemoglobin A1C shows what the person's average blood glucose level was for that period of time.
