Metabolite Identification
Common NameHemimellitene
DescriptionHemimellitene, also known as hemellitol, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. Hemimellitene is possibly neutral. Outside of the human body, Hemimellitene is found, on average, in the highest concentration within black walnuts. Hemimellitene has also been detected, but not quantified in, corns and sweet cherries. This could make hemimellitene a potential biomarker for the consumption of these foods. Hemimellitene, with regard to humans, has been found to be associated with several diseases such as asthma and ulcerative colitis; hemimellitene has also been linked to the inborn metabolic disorder celiac disease. These are compounds containing a benzene ring which bears a methane group.
