Chemical Information
FooDB Name(E)-2-Nonenal
Description(E)-2-Nonenal, also known as (2E)-nonenal or 2-trans-nonenal, 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. Thus, (e)-2-nonenal is considered to be a fatty aldehyde lipid molecule (E)-2-Nonenal is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (E)-2-Nonenal may be a unique S. cerevisiae (yeast) metabolite (E)-2-Nonenal is an aldehydic, citrus, and cucumber tasting compound (E)-2-Nonenal has been detected, but not quantified in, several different foods, such as fats and oils, rocket salad (ssp.), asparagus, fruits, and blackberries. This could make (e)-2-nonenal a potential biomarker for the consumption of these foods.
