Product Overview :
This rapid and simple enzymatic colorimetric method is used for the quantitative determination of D-glucose in food stuffs such as baking agents, diet beer and dietetic foods, as well asin pharmaceuticals, cosmetics and biological samples. The analysis of D-glucose in foodstuffs is normally performed inconjunction with D-fructose, maltose and sucrose.
Description :
D-Glucose occurs widely in plants and animals. It is an essential component of carbohydrate metabolism and occurs frequently in the free form along with D-fructose and sucrose. However, the more important forms are those of di- (lactose, maltose, sucrose), tri-, oligo- and polysaccharides (dextrins, starch, cellulose). It is present in significant quantities in honey, wine and beer, and a range of solid foodstuffs such as bread and pastries, chocolate and candies. Measurement of D-glucose is extremely important in biochemistry and clinical analysis, as well as in food analysis; it is mostly determined along with other carbohydrates.

Kit Components :
Solution 1 (×2). GOD-POD reagent buffer (30 mL, pH 7.4), 0.42 M Potassium fosfate, 0.35 M p-hydroxybenzoic acid and sodium azide (0.64% w/v) as a preservative. Stable for 3 yearsat 4 °C.
Dilute the contents of bottle to 1 L with distilled water and use immediately.
Solution 2 (×2). GOD-POD reagent enzymes. Freeze-dried powder of glucose oxidase (GOD; >12,000 U), peroxidase (POD; >650 U) and 4-aminoantipyrine (80 mg). Stable for 5 years at -20 °C.
