Metabolite Identification
Common NameXanthine
DescriptionXanthine, also known as Xan or 2,6-dioxopurine, 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 exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Xanthine exists in all living species, ranging from bacteria to humans. Xanthine is a potentially toxic compound. Xanthine has been found to be associated with several diseases known as crohn's disease, colorectal cancer, degenerative disc disease, and cystic fibrosis; also xanthine has been linked to the inborn metabolic disorders including lesch-nyhan syndrome.
