Both the increase of lipid peroxidation reaction rate and the shortening of the latent period were dependent on the pre-existed lipid peroxides in liposomes. Al3+ accelerated the oxidation of Fe2+ in liposomal system only when liposomes contain pre-exist peroxides. The addition of Al3+ to the liposomal suspension resulted in a marked increase of turbidity of the suspension and decrease of fluidity of the liposomes.

这可能是因为在脂质体存在的条件下，Al3＋加速了Fe2＋的氧化，且加速作用与脂质体中原先存在的过氧化物的含量有关；另一方面，Al3＋可以引起脂质体的聚集，表现为浊度的增加；测量脂质体上标记的脂肪酸自旋标记物5－ Doxyl stearic acid 的ESR 波谱发现： Al3＋降低了脂质体的膜脂的流动性。
