Chemical Information

FooDB Name

2-Hexenal

Description

2-Hexenal, also known as 2-hexenaldehyde or 3-propyl-acrolein, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. 2-Hexenal is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Hexenal is a sweet, almond, and apple tasting compound. 2-Hexenal has been detected, but not quantified in, several different foods, such as sweet cherries, soy beans, black elderberries, common walnuts, and cabbages. This could make 2-hexenal a potential biomarker for the consumption of these foods. 2-Hexenal is a potentially toxic compound.
