(E)-4-Oxo-2-nonenal  (Synonyms: 4-ONE)

(E)-4-Oxo-2-nonenal (4-ONE) is one of the major hemolytic decomposition products of lipid hydroperoxides. (E)-4-Oxo-2-nonenal is a major product of the FeII-mediated breakdown of lipid hydroperoxides. (E)-4-Oxo-2-nonenal is a potent transient receptor potential ankyrin 1 (TRPA1) agonist^[1][2][3].
