Metabolite Identification
Common Name8-Prenylkaempferol
Description8-Prenylkaempferol belongs to the class of organic compounds known as 8-prenylated flavones. These are flavones that features a C5-isoprenoid substituent at the 8-position. Thus, 8-prenylkaempferol is considered to be a flavonoid. Based on a literature review very few articles have been published on 8-Prenylkaempferol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 8-prenylkaempferol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 8-Prenylkaempferol 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.
