'''Xylose''' is a [[monosaccharide]] of the [[aldopentose]] type, which means it contains five carbon atoms and includes an [[aldehyde]] functional group. It is a naturally occurring sugar found in the [[hemicellulose]] of plant cell walls and is a significant component of [[wood]] and [[biomass]]. Xylose is classified as a [[reducing sugar]] and is often used in the production of [[xylitol]], a sugar substitute.

==Structure and Properties==
Xylose has the chemical formula C5H10O5. It exists in two forms: D-xylose and L-xylose, with D-xylose being the more common isomer found in nature. The structure of D-xylose can be represented as:

Xylose is a crystalline solid that is soluble in water and has a sweet taste. It is less sweet than [[glucose]] and [[sucrose]].

==Occurrence==
Xylose is a major component of [[hemicellulose]], which is a complex carbohydrate found in the cell walls of plants. It is particularly abundant in hardwoods, straw, and corncobs. The hydrolysis of hemicellulose releases xylose, which can then be fermented to produce biofuels and other chemicals.

==Metabolism==
In humans, xylose is absorbed in the small intestine and is metabolized by the liver. It is not as readily utilized by the body as glucose, and a significant portion of ingested xylose is excreted in the urine. Xylose is used in medical tests to assess the absorptive capacity of the small intestine.

==Uses==
Xylose is used in various industrial applications, including:
* The production of [[xylitol]], a sugar alcohol used as a sweetener in sugar-free products.
* As a precursor for the production of [[furfural]], a chemical used in the manufacture of resins and solvents.
* In the food industry as a sweetener and flavor enhancer.

==Health Effects==
Xylose is generally considered safe for consumption. It has a low glycemic index, making it suitable for people with [[diabetes]]. However, excessive consumption may lead to gastrointestinal discomfort.
