Metabolite Identification
Common Namebeta-Endorphin (1-31)
Descriptionbeta-Endorphin (1-31) belongs to the class of organic compounds known as polypeptides. These are peptides containing ten or more amino acid residues. Based on a literature review a significant number of articles have been published on beta-Endorphin (1-31). This compound has been identified in human blood as reported by (PMID: 31557052 ). Beta-endorphin (1-31) is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically beta-Endorphin (1-31) 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.
