Metabolite Identification

Common Name

Khellin

Description

khellin, also known as quelina, belongs to the class of organic compounds known as furanochromones. These are polycyclic aromatic compounds containing a furan ring fused to a 1-benzopyran-4-one ring system. Thus, khellin is considered to be an aromatic polyketide lipid molecule. khellin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. This compound has been identified in human blood as reported by (PMID: 31557052 ). Khellin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Khellin 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.
