Metabolite Identification
Common NameN-Acetyl-DL-phenylalanine
DescriptionN-acetylphenylalanine, also known as afalanina, belongs to the class of organic compounds known as phenylalanine and derivatives. Phenylalanine and derivatives are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-acetylphenylalanine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on N-acetylphenylalanine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-acetyl-dl-phenylalanine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Acetyl-DL-phenylalanine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
