Chemical Information
FooDB NameCyclopentanone
DescriptionCyclopentanone, also known as dumasin or ketocyclopentane, belongs to the class of organic compounds known as cyclic ketones. These are organic compounds containing a ketone that is conjugated to a cyclic moiety. Cyclopentanone is an extremely weak basic (essentially neutral) compound (based on its pKa). Cyclopentanone is a minty tasting compound. Cyclopentanone has been detected, but not quantified in, several different foods, such as strawberry guava, pigeon pea, lindens, persimmons, and purple mangosteens. This could make cyclopentanone a potential biomarker for the consumption of these foods.
