Metabolite Identification
Common NameN-Methyl-L-isoleucine
DescriptionN-methyl-L-isoleucine, also known as meile, belongs to the class of organic compounds known as isoleucine and derivatives. Isoleucine and derivatives are compounds containing isoleucine or a derivative thereof resulting from reaction of isoleucine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-methyl-L-isoleucine is a very strong basic compound (based on its pKa).
