| glucose dehydrogenases | <enzyme> D-glucose:1-oxidoreductases. Catalyses the oxidation of d-glucose to d-glucono-gamma-lactone and reduced acceptor. Any acceptor except molecular oxygen is permitted. Registry number: EC 1.1.1. (12 Dec 1998) |
|---|---|
| glucose-fructose oxidoreductase | <enzyme> Isolated from zymomonas mobilis; catalyses the formation of sorbitol and glucono-delta-lactone from glucose and fructose; enzyme contains tightly bound nadp+ Registry number: EC 1.1.99.- (26 Jun 1999) |
| glucose intolerance | A pathological state in which the fasting plasma glucose level is less than 140 mg per deciliter and the 30-, 60-, or 90-minute plasma glucose concentration following a glucose tolerance test exceeds 200 mg per deciliter. This condition is seen frequently in diabetes mellitus but also occurs with other diseases. (12 Dec 1998) |
| glucose isomerase | <enzyme> An isomerase enzyme which converts the sugar glucose into the sugar fructose. Fructose is a structural isomer of glucose. (09 Oct 1997) |
| glucose oxidase | <enzyme> An enzyme which converts glucose into gluconic acid and hydrogen peroxide (H2O2). It is used to help diagnose diabetes by determining if glucose is present in the patients urine, if the glucose is present, the hydrogen peroxide produced in the reaction can be detected by reacting it with an indicator to change the colour of the urine. (09 Oct 1997) |
| glucose oxidase method | <chemical pathology> A highly specific method for measurement of glucose in serum or plasma by reaction with glucose oxidase, in which gluconic acid and hydrogen peroxide are formed. (05 Mar 2000) |
| glucose oxidase paper strip test | <chemical pathology> A qualitative test for glucose in the urine, in which glucose is oxidised to gluconic acid by glucose oxidase; a specific test, unless ascorbic acid is present. (05 Mar 2000) |
| glucose oxyhydrase | <enzyme> An enzyme which converts glucose into gluconic acid and hydrogen peroxide (H2O2). It is used to help diagnose diabetes by determining if glucose is present in the patients urine, if the glucose is present, the hydrogen peroxide produced in the reaction can be detected by reacting it with an indicator to change the colour of the urine. (09 Oct 1997) |
| glucose-phosphate isomerase | <enzyme> An enzyme that catalyses the reversible interconversion of d-fructose 6-phosphate and d-glucose-6-phosphate; a part of glycolysis and gluconeogenesis; glucosephosphate isomerase deficiency is an inherited disorder resulting in liver glycogenesis and haemolytic anaemia. Synonym: hexosephosphate isomerase, phosphohexomutase, phosphohexose isomerase. (05 Mar 2000) |
| glucose phosphomutase | <enzyme> An enzyme that catalyses the conversion of alpha d-glucose 1-phosphate to alpha d-glucose-6-phosphate. Chemical name: alpha-D-Glucose 1,6-phosphomutase Registry number: EC 5.4.2.2 (12 Dec 1998) |
| glucose related protein | <protein> One of the stress related proteins: identical to endoplasmin. (18 Nov 1997) |
| glucose solution, hypertonic | Solution that is usually 10 percent glucose but may be higher. An isotonic solution of glucose is 5 percent. (12 Dec 1998) |
| glucose tolerance factor | A water-soluble complex containing chromium needed for normal glucose tolerance. (05 Mar 2000) |
| glucose tolerance test | <chemical pathology, investigation> A special test where the blood glucose is measure in intervals after a glucose-rich meal is taken, a test used for diagnosing diabetes. (27 Sep 1997) |
| glycerol-3-phosphate - glucose phosphotransferase | <enzyme> Catalyses the formation of glycerol and glucose-6-phosphate Registry number: EC 2.7.1.142 Synonym: gro3p-glucose transphorylase, glycerol 3-phosphate-glucose transphorylase (26 Jun 1999) |
