Metabolite Identification
Common NameAlacepril
DescriptionAlacepril belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Based on a literature review very few articles have been published on Alacepril. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alacepril is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Alacepril 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.
