Biotin is classified as a [[heterocyclic compound]], with a sulfur-containing [[tetrahydrothiophene]] ring fused to a [[ureido]] group. A C5-carboxylic acid side chain is appended to the former ring. The ureido ring, containing the −N−CO−N− group, serves as the carbon dioxide carrier in carboxylation reactions. Biotin is a [[coenzyme]] for five [[carboxylase]] enzymes, which are involved in the [[catabolism]] of [[amino acid]]s and [[fatty acid]]s, synthesis of [[fatty acid]]s, and [[gluconeogenesis]]. [[Biotinylation]] of [[histone]] proteins in nuclear [[chromatin]] plays a role in chromatin stability and gene expression.</div>FuzzyBot
