Abstract

The question has been addressed whether the side chain contributes to the antioxidant activity of Ubiquinones. The length, the chemical composition and structure of the chain have been considered. The effect of the actual concentration of the quinone in egg lecithin vesicles has been investigated by means of both UV spectroscopy and time resolved fluorescence quenching experiments of 12-AS. The results indicate that the antioxidant properties of the quinone do not seem to depend on the side chain.

摘要

泛醌的侧链是否对其抗氧化活性有贡献这一问题已经得到探讨。人们已经考虑了侧链的长度、化学组成和结构。通过紫外光谱法以及对12-AS进行时间分辨荧光猝灭实验，研究了卵磷脂囊泡中醌的实际浓度的影响。结果表明，醌的抗氧化特性似乎并不取决于侧链。
