Chemical Information
FooDB Name(E)-2-Heptenoic acid
Description2-Heptenoic acid, also known as 7:1, N-5 trans or (e)-2-heptenoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. 2-Heptenoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
