Production of hydroxy unsaturated fatty acids using crude lipoxygenase obtained from infected rice plants
In order to explore the oxidation mode of lipoxygenase (LOX) obtained from infected rice plants, typical unsaturated fatty acids (3-8) were treated with LOX and oxygen. It was observed that ω-10 and ω-6 positions of unsaturated fatty acids were oxidized predominantly in the cases of exotic ω-6 (4 and 5) and ω-3 (7 and 8) series, respectively. In the case of endogenous fatty acids (3 and 6), oxidation at ω-6 position predominated. All the allylic alcohols obtained by reduction of the oxidation products with NaBH4 possess S-configuration.
