Chemical Information
FooDB Name5-Hydroxyisourate
Description5-Hydroxyisourate belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. 5-Hydroxyisourate is an extremely weak basic (essentially neutral) compound (based on its pKa). 5-Hydroxyisourate exists in all living organisms, ranging from bacteria to humans. 5-Hydroxyisourate has been detected, but not quantified in, several different foods, such as green beans, adzuki beans, asian pears, black mulberries, and yellow wax beans. This could make 5-hydroxyisourate a potential biomarker for the consumption of these foods.
