Metabolite Identification
Common NamePurine
DescriptionPurine, also known as purine base or 1H-purine, belongs to the class of organic compounds known as purines and purine derivatives. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring. Purine exists as a solid, possibly soluble (in water), and a strong basic compound (based on its pKa) molecule. Purine exists in all living species, ranging from bacteria to humans.
