Metabolite Identification

Common Name

N-methylvaline

Description

N-methylvaline, also known as maval, belongs to the class of organic compounds known as valine and derivatives. Valine and derivatives are compounds containing valine or a derivative thereof resulting from reaction of valine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-methylvaline is a very strong basic compound (based on its pKa). An optically active form of N-methylvaline having L-configuration.
