Chemical Information
FooDB Name3-Methylxanthine
Description3-Methylxanthine, also known as 3 MX, 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. 3-Methylxanthine has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 3-methylxanthine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 3-Methylxanthine.
