Acetylphenylalanine is a hazardous amphipathic metabolite of phenylalanine. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine. Acetylphenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC] in the pathway phenylalanine metabolism. (KEGG; Wikipedia) [HMDB]
