Metabolite Identification
Common NamePhenyl-Leucine
DescriptionPhenyl-Leucine, also known as L-leucine, N-phenyl- is classified as a leucine or a leucine derivative. Leucines are compounds containing leucine or a derivative thereof resulting from reaction of leucine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Phenyl-Leucine is considered to be practically insoluble (in water) and acidic. (ChemoSummarizer)
