Metabolite Identification
Common NameMurabutide
DescriptionMurabutide, also known as amaig-be, belongs to the class of organic compounds known as peptides. Peptides are compounds containing an amide derived from two or more amino carboxylic acid molecules (the same or different) by formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another. Based on a literature review a significant number of articles have been published on Murabutide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Murabutide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Murabutide 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.
