Metabolite Identification
Common NameUric acid
DescriptionUric acid, also known as urate or acid, uric, 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. Uric acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Uric acid exists in all living species, ranging from bacteria to humans. Uric acid is a potentially toxic compound. Uric acid has been found to be associated with several diseases known as fanconi syndrome, impaired glucose tolerance, and d-lactic acidosis; also uric acid has been linked to several inborn metabolic disorders including atic deficiency and lesch-nyhan syndrome.
