代谢
多环芳烃(PAHs)的代谢发生在所有组织中,通常通过细胞色素P-450及其相关酶进行。多环芳烃被代谢成反应性中间体,其中包括环氧中间体、二氢二醇、酚、醌以及它们的各种组合。酚、醌和二氢二醇都可以与葡萄糖苷酸和硫酸酯结合;醌还可以形成谷胱甘肽结合物。
PAH metabolism occurs in all tissues, usually by cytochrome P-450 and its associated enzymes. PAHs are metabolized into reactive intermediates, which include epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations. The phenols, quinones, and dihydrodiols can all be conjugated to glucuronides and sulfate esters; the quinones also form glutathione conjugates. (L10)
