Chemical Information
FooDB NameHexen-2-al
Description2-hexenal, also known as hexobarbital, sodium or 3-propyl-acrolein, is a member of the class of compounds known as medium-chain aldehydes. Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. 2-hexenal is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-hexenal is a sweet, almond, and apple tasting compound and can be found in a number of food items such as apple, burdock, pot marjoram, and soy bean, which makes 2-hexenal a potential biomarker for the consumption of these food products. 2-hexenal can be found primarily in blood, feces, and saliva. 2-hexenal is a non-carcinogenic (not listed by IARC) potentially toxic compound.
