Metabolite Identification
Common NameL-Proline, 1-(1-L-leucyl-L-prolyl)-
DescriptionL-Proline, 1-(1-L-leucyl-L-prolyl)- 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 L-Proline, 1-(1-L-leucyl-L-prolyl)-. This compound has been identified in human blood as reported by (PMID: 31557052 ). L-proline, 1-(1-l-leucyl-l-prolyl)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically L-Proline, 1-(1-L-leucyl-L-prolyl)- 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.
