Chemical Information
FooDB Name(E)-2-Hexenoic acid
Description(E)-2-Hexenoic acid is fatty acid formed by the action of fatty acid synthases from acetyl-CoA and malonyl-CoA precursors. It is involved in the fatty acid biosynthesis pathway. Specifically, it is the product of reaction between (R)-3-Hydroxyhexanoic acid and fatty-acid Synthase. (E)-2-Hexenoic acid is found in many foods, some of which are alcoholic beverages, fruits, tea, and fats and oils. It is used as flavouring agent.
