Chemical Information
FooDB NameD-Xylopyranose
DescriptionD-Xylose, also known as xylose or xylopyranose, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. D-Xylose is an extremely weak basic (essentially neutral) compound (based on its pKa). D-Xylose exists in all living species, ranging from bacteria to humans. D-Xylose has been detected, but not quantified in, flaxseeds. This could make D-xylose a potential biomarker for the consumption of these foods. D-Xylose is a potentially toxic compound.
