Chemical Information
FooDB NameD-Xylose
DescriptionD-Xylose is a flavouring ingredient; sweetener. It is found in straw, corncobs, pecan shells, carrot, dandelion, german camomile, and sweet orange. D-Xylose is a sugar first isolated from wood, and named for it. D-Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional group. It is the precursor to hemicellulose, one of the main constituents of biomass (Wikipedia). Xylose in the urine is a biomarker for the consumption of fruits.
