Seed from maize (corn) Zea mays provides a ready source of 9-lipoxygenase that oxidizes linoleic acid and Iinolenic acid into 9(5)-hydroperoxy-1 0(8, 12(Zl-octadecadienoic acid and 9(SJ-hydroperoxy-1 0(£), 12(Zj, 15(Zl-octadecatrienoic acid, respectively. Corn seed has a very active hydroperoxide-decomposing enzyme, allene oxide synthase (AOS), which must be removed prior to oxidizing the fatty...
