CYP酶在PUFAs中的作用-哺乳动物长链 n-6 和 n-3 多不饱和脂肪酸 （PUFA） 的生物合成途径。
花生四烯酸（AA）的生物活化。生理活性AA代谢物的产生由环氧合酶（COX），脂氧合酶（LOX）和细胞色素P450（CYP）酶启动。
n-6多不饱和脂肪酸的细胞色素P450（CYP）依赖性代谢。所描述的结构式是各个CYP亚型以区域和立体选择性方式产生的各种环氧和羟基代谢物的例子。环氧代谢物通过可溶性环氧化物水解酶（sEH）水解为相应的邻二醇
细胞色素 P450 （CYP） 依赖性 n−3 多不饱和脂肪酸的代谢。与它们的n-6对应物类似，n-3多不饱和脂肪酸主要通过羟基化和环氧化代谢，如所选代谢物的结构式所示。如文中详细描述，ω-3 双键为许多不同的 CYP 亚型提供了首选的环氧化位点。环氧代谢物通过可溶性环氧化物水解酶（sEH）水解为相应的邻二醇。
