Metabolite Identification
Common NameIsoleucyl-prolyl-proline
DescriptionIsoleucyl-prolyl-proline belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Based on a literature review a significant number of articles have been published on Isoleucyl-prolyl-proline. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isoleucyl-prolyl-proline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isoleucyl-prolyl-proline 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.
