Chemical Information

FooDB Name

3-Pentanone

Description

3-pentanone, also known as diethyl ketone or ethyl propionyl, is a member of the class of compounds known as ketones. Ketones are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, 3-pentanone is considered to be an oxygenated hydrocarbon lipid molecule. 3-pentanone is soluble (in water) and an extremely weak acidic compound (based on its pKa). 3-pentanone is an acetone and ethereal tasting compound and can be found in a number of food items such as strawberry guava, ceylon cinnamon, beech nut, and pak choy, which makes 3-pentanone a potential biomarker for the consumption of these food products.
