Metabolite Identification
Common NameBiotin
DescriptionBiotin, also known as D-biotin or biotin ratiopharm, belongs to the class of organic compounds known as biotin and derivatives. These are organic compounds containing a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. Biotin is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. Biotin exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Biotin exists in all living species, ranging from bacteria to humans. In cattle, biotin is involved in the metabolic pathway called the biotin metabolism pathway. Biotin is a potentially toxic compound.
