D-Xylose is a sugar originally isolated from wood. D-Xylose is a colorless to white crystalline powder that is used in food products such as breads, butter, and beverage industry as flavoring agent and sweetener. Specifically, D-Xylose is used to sweeten products intended for use by obese and diabetic customers because it is a non-caloric sweetener. It has a cool and refreshing taste and has the same sweetness as sucrose, and it is often used to sweeten a wide variety of foods and beverages such as spices, meat products, butter, etc. D-Xylose is a sugar widely used as diabetic sweetener in food and beverage. is a sugar first isolated from wood, and named for it. Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes a formyl functional group. It is derived from hemicellulose, one of the main constituents of biomass. Like most sugars, it can adopt several structures depending on conditions. With its free carbonyl group, it is a reducing sugar. D-xylose absorbtion test has been used for diagnosis of intestinal malabsorption.

Sample Use Guides
Xylose Absorption Test for determining cause of malabsorption. The participant will be asked to drink 8 ounces (240 ml) of water that contains 25 grams of a sugar called d-xylose. The amount of d-xylose that comes out in your urine over the next 5 hours will be measured. The participant may have a blood sample collected at 1 and 3 hours after drinking the liquid. The amount of urine produced over a 5-hour period is also determined.
Route of Administration:
Oral
To clarify the relationship between NAD(P)+/NAD(P)H redox balances and the metabolisms of xylose or xylitol as carbon sources, authors analyzed aerobic and anaerobic batch cultures of recombinant Saccharomyces cerevisiae in a complex medium containing 20 g/L xylose or 20 g/L xylitol at pH 5.0 and 30°C.
