Conclusion The major metabolic pathway of TBHQ in rat serum should be phase ⅱ reaction ( biotransformed by glucuronidation or arylsulfatation), although a small quantity of TBHQ would be metabolized by phase ⅰ reaction that might be oxidation. 结论TBHQ在大鼠血清中主要经Ⅱ相反应(与硫酸或葡萄糖醛酸结合)代谢,此外少量TBHQ会发生Ⅰ相反应,推测为氧化反应,生成的二羟基化物与谷氨酸结合。
