实验模型膜，其中泛醌被纳入，进行，以澄清泛醌可以防止或控制链脂质过氧化反应的生物膜的机制。比较行为的泛醌含有囊泡与β-胡萝卜素含有囊泡，我们认为，泛醌的抗氧化作用的一个可能的解释可能是抑制单线态氧和结构上的影响脂质双层抑制氢过氧化物分解。
Experiments with model membranes, in which ubiquinone was incorporated, were performed in order to clarify the mechanism by which ubiquinone can prevent or control chain lipid peroxidation in biomembranes. Comparing the behavior of ubiquinone-containing vesicles with beta-carotene containing vesicles we suggest that a possible explanation of the ubiquinone antioxidant effect could be to scavenge singlet oxygen and to affect structurally the lipid bilayer inhibiting hydroperoxide decomposition.
