Metabolite Identification
Common NameMalabaricone B
DescriptionMalabaricone B belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Malabaricone B is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Malabaricone b is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Malabaricone B 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.
