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.
为了探索从感染的
水稻植物中获得的脂氧化酶(LOX)的氧化模式,通过LOX和
氧气处理了典型的不饱和
脂肪酸(3—8)。观察到在异源ω-6(4和5)和ω-3(7和8)系列的不饱和
脂肪酸中,主要在ω-10和ω-6位发生氧化。而在内源性
脂肪酸(3和6)的情况下,ω-6位的氧化占主导地位。通过用NaBH4还原氧化产物获得的所有
烯丙醇均具有S构型。
