Metabolite Identification
Common NameLignan
DescriptionLignan, also known as neolignan, belongs to the class of organic compounds known as aryltetralin lignans. These are lignans with a structure based on the 1-phenyltetralin skeleton. Based on a literature review a significant number of articles have been published on Lignan. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lignan is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lignan 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.
