Metabolite Identification
Common NameL-Hydroxyprolylglycine
DescriptionH-Hyp-gly-OH 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 H-Hyp-gly-OH. This compound has been identified in human blood as reported by (PMID: 31557052 ). L-hydroxyprolylglycine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically L-Hydroxyprolylglycine 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.
