Description

Plant oxylipins are a diverse class of lipid metabolites that are derived from the oxidation of unsaturated fatty acids. Oxylipins formed in plants include fatty acid hydroperoxides, hydroxy-, oxo-, or keto-fatty acids, divinyl ethers, volatile aldehydes, or the plant hormone Jasmonic Acid (JA).
