Oxidation glucose to gluconate

In presence of the enzyme glucose oxidase, an aqueous solution of glucose undergoes oxidation to gluconic acid with formation of hydrogen peroxide which can be determined by anodic oxidation at a fixed potential. [Pg.639]

Glucose can be oxidized to gluconic acid by oxygen (4.38) in the presence of palladium on alumina, a palladium-bismuth catalyst, or a platinum-bismuth catalyst in 99-100% yield.186... [Pg.82]

Glucose oxidase is immobilized in a polyacrylamide matrix. Oxygen and quinone which serve as mediators are reduced to hydrogen peroxide and hydroquinone, respectively. Since their oxidation starts at E, > 0.7-0.9 V, it is possible to displace the initial potential for the oxidation of glucose by 0.6-0.8 V towards positive values compared to its stationary electrochemical oxidation to gluconic acid on platinum. ... [Pg.279]

More drastic oxidation of aldoses with hypoiodite leads to keto acids and finally to cleavage of carbon-carbon bonds. Honig and Tempus 199) claimed to have oxidized glucose stepwise to gluconic acid, 2-ketogluconic acid, and n-arabonic acid. However, other workers claim that the main product is 5-ketogluconic acid 200),... [Pg.344]

A dipstick test manufactured by the Ames company for the detection of glucose in urine. It is based on the glucose oxidase reaction, in which glucose is oxidized to gluconic acid and hydrogen peroxide. Peroxidase then catalyses the oxidation of o-tolidine by hydrogen peroxide to produce a blue colour. [Pg.86]
