2-Methylbutyrylglycine, or 2-MBG, is a metabolite generated in the body during the breakdown of specific amino acids. It falls under the acylglycines family and is derived from branched-chain amino acids. The detection of 2-Methylbutyrylglycine in urine samples can serve as an indicator of the presence of these disorders. 2-Methylbutyrylglycine influences the regulation of branched-chain amino acid metabolism. Some suggest that 2-Methylbutyrylglycine may act as an inhibitor of isovaleryl-CoA dehydrogenase, a key enzyme involved in the breakdown of isoleucine.
