Metabolite Identification
Common NamePhenylethylmalonamide
DescriptionPhenylethylmalonamide, also known as PEMA or ethylphenylmalonamide, belongs to the class of organic compounds known as phenylacetamides. These are amide derivatives of phenylacetic acids. Phenylethylmalonamide is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on Phenylethylmalonamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phenylethylmalonamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phenylethylmalonamide 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.
