Xylose or wood sugar is an aldopentose — a monosaccharide containing five carbon atoms and including an aldehyde functional group. It has chemical formula C5H10O5. Xylose is found in the embryos of most edible plants.

It is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid (formally, N-acetylneuraminic acid).

Xylose is used to test for malabsorption by administering to the patient in water after fasting. If xylose is detected in blood and/or urine within the next few hours, it has been absorbed by the intestines.[1]
