1·These results are significant because PAH diol epoxides react readily with DNA, induce mutations, and are considered to be ultimate carcinogens of multiple PAH in cigarette smoke.
这些结果具有重要意义，因为多环芳烃二醇环氧化物极易与DNA反应，进而导致变异，因此被视为香烟烟雾中所含多种多环芳烃中最重要的致癌物质。
2·Juvenile hormone (JH) metabolism enzymes, including JH esterase, JH epoxide hydrolase and JH diol kinase, catalyze JH to metabolize.
保幼激素的代谢由保幼激素酯酶、保幼激素环氧水解酶和保幼激素二醇激酶等共同催化完成。
