| FooDB Name | Xanthine |
|---|
| Description | Xanthine 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. Xanthine is an extremely weak basic (essentially neutral) compound (based on its pKa). Xanthine is found, on average, in the highest concentration within milk (cow). Xanthine has also been detected, but not quantified in, several different foods, such as fenugreeks, ucuhuba, roselles, allspices, and garland chrysanthemums. This could make xanthine a potential biomarker for the consumption of these foods. |
