| deficiency, glucose-6-phosphate dehydrogenase | Deficiency of G6PD is the commonest disease-causing enzyme defect in humans affecting an estimated 400 million people. The G6PD gene is on the X chromosome. Males with the enzyme deficiency develop anaemia due to breakup of their red blood cells when they are exposed to oxidant drugs such as the antimalarial primaquine, the sulfonamide antibiotics or sulfones, naphthalene moth balls, or fava beans.

| d-glucose | D-Glucose;a dextrorotatory monosaccharide (hexose) found in the free state in fruits and other parts of plants, and combined in glucosides, disaccharides (often with fructose in sugars), oligosaccharides, and polysaccharides; it is the product of complete hydrolysis of cellulose, starch, and glycogen. Free glucose also occurs in the blood (normal human concentration, 70 to 110 mg per 100 ml); in diabetes mellitus, it appears in the urine. The epimers of d-glucose are d-allose, d-mannose, d-galactose, and l-idose. Dextrose should not be confused with the l-isomer which is sinistrose. Synonym: cellohexose. (05 Mar 2000) |

| dTDP-D-glucose synthase | <enzyme> Catalyses the formation of dtdp-d-glucose by using glucose-1-phosphate and dttp as substrates; rfba is a dual function enzyme; rfba is also a phosphomannose isomerase-guanosine diphosphomannose pyrophosphorylase; see record of pmi-GMP Registry number: EC 2.7.7.- Synonym: rfba protein, deltatdp-glucose synthase, tyla1 gene product, rfba gene product (26 Jun 1999) |
| impaired glucose tolerance | Blood glucose (sugar) levels higher than normal but not high enough to be called diabetes. People with impaired glucose tolerance may or may not develop diabetes. Other names (no longer used) for impaired glucose tolerance are borderline, subclinical, chemical, or latent diabetes. (30 Mar 1998) |
| test, glucose tolerance | After fasting, a specific amount (100 grams) of glucose is given by mouth, and the blood levels of this sugar are measured every hour. Normally, the blood glucose should return to normal within 2 to 2 1/2 hours. The gtt is considered a classic test of carbohydrate metabolism. It is much used in the diagnosis of diabetes. The gtt depends on a number of factors including the ability of the intestine to absorb glucose, the power of the liver to take up and store glucose, the capacity of the pancreas to produce insulin, and the amount of active insulin.
