Metabolite Identification
Common Name4-Hexen-3-one
Description4-Hexen-3-one (CAS: 2497-21-4), also known as 2-hexen-4-one or ethyl 1-propenyl ketone, belongs to the class of organic compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR'. 4-Hexen-3-one is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-Hexen-3-one is an ethereal, green, and metallic tasting compound. Outside of the human body, 4-hexen-3-one has been detected, but not quantified in, several different foods, such as pepper (C. baccatum), tea leaf willows, turmerics, sweet oranges, and other soy products. This could make 4-hexen-3-one a potential biomarker for the consumption of these foods. 4-Hexen-3-one is a flavouring ingredient.
