This approach includes the use of allylic functionality in the latex, alkyd-acrylic latexes, latexes incorporating soya oil in the polymer backbone or side chain, and the use of small amounts of diene monomers (e.g., butadiene, pentadiene) in the latex.
They catalyze the hydroperoxidation of pentadiene moieties of long-chain fatty acids, initiating biosynthesis of regulator compounds, the best known of which in plants are the jasmonates.
Each isozyme independently catalyzes the hydroperoxidation of polyunsaturated fatty acids that contain a cis, cis, -1,4- pentadiene moiety (Axelrod et al., 1981).
