reactivity of unsaturated fatty acids with cumylperoxyl radical, which is expressed by the additive contributions of the reactivity of active hydrogens from the 1,4-pentadiene subunit and those of the allylic subunit; the kinetic isotope effect on the hydrogen transfer reactions (KIE = 6.1) is significantly smaller than that observed for lipoxygenase (KIE = 81).
一个简单的加性规则就在于不饱和脂肪酸与枯基过氧自由基的氢转移反应性,其表现为来自1,4-戊二烯亚基和烯丙基亚基的活泼氢的反应性的加和贡献。氢转移反应的动力学同位素效应(KIE = 6.1)明显小于脂氧合酶(KIE = 81)。
