Metabolite Identification

Common Name

Pyroglutamyl-histidyl-proline

Description

1-(2-{[hydroxy(5-hydroxy-3,4-dihydro-2H-pyrrol-2-yl)methylidene]amino}-3-(1H-imidazol-5-yl)propanoyl)pyrrolidine-2-carboxylic acid 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 very few articles have been published on 1-(2-{[hydroxy(5-hydroxy-3,4-dihydro-2H-pyrrol-2-yl)methylidene]amino}-3-(1H-imidazol-5-yl)propanoyl)pyrrolidine-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pyroglutamyl-histidyl-proline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pyroglutamyl-histidyl-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.
