Metabolite Identification
Common NameN-Methylalanine
DescriptionN-Methylalanine, also known as (S)-2-methylaminopropanoate or N-methyl-L-alanine, is classified as an alanine or an alanine derivative. Alanines are compounds containing alanine or a derivative thereof resulting from reaction of alanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-Methylalanine is considered to be soluble (in water) and acidic. (ChemoSummarizer)
