Metabolite Identification
Common Name(2E)-2-Heptenal
Description, also known as (e)-2-heptenal or 3-butylacrolein, 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, is considered to be a fatty aldehyde lipid molecule. is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). has been detected in multiple biofluids, such as saliva and blood. Within the cell, is primarily located in the cytoplasm. exists in all eukaryotes, ranging from yeast to humans. is an almond, fat, and fatty tasting compound that can be found in a number of food items such as roselle, safflower, watermelon, and common grape. This makes a potential biomarker for the consumption of these food products. is a potentially toxic compound.
