[13C]-Xanthine

[13C]-Xanthine is a stable isotope-labeled form of xanthine, which is a purine base found in all body tissues and fluids. Xanthine is a metabolite of caffeine and is involved in the production of uric acid, which is a waste product excreted by the kidneys. Xanthine has been used in the diagnosis of gout, hyperuricemia, and other metabolic disorders. [13C]-Xanthine is used in metabolic studies to track the fate of xanthine in the body. The stable isotope-labeled form of xanthine allows researchers to distinguish between the labeled and unlabeled xanthine in the body. By following the labeled xanthine, researchers can learn more about the metabolic pathways and the fate of xanthine in the body. Chemically, [13C]-Xanthine is a purine base with a molecular weight of 158.12 g/mol. It is a white powder that is soluble in water. The stable isotope-labeled carbon in the molecule is located at the C-13 position, which is the carbon atom next to the nitrogen atom in the purine ring. In summary, [13C]-Xanthine is a valuable tool in metabolic studies that allows researchers to track the fate of xanthine in the body. The stable isotope-labeled form of xanthine helps researchers learn more about the metabolic pathways and the fate of xanthine in the body.
