The influence of UV-irradiation on the electrical stability of black lipid membranes (BLM) prepared from mitochondrial lipids has been studied. The breakdown voltage of BLM is shown to decrease as a result of photoperoxidation of unsaturated fatty acid chains of phospholipids. It appears reasonable to assume that the UV-radiation induces the dielectric breakdown and alteration of functions of cell membranes (i.e. UV-uncoupling of oxidative phorylation in mitochondria).
研究了紫外线辐射对由线粒体脂质制备的黑色脂质膜(BLM)电稳定性的影响。结果表明,由于磷脂不饱和脂肪酸链的光过氧化作用,BLM的击穿电压降低。可以合理地假设,紫外线辐射会诱导细胞膜的介电击穿和功能改变(即线粒体中氧化磷酸化的紫外线解偶联)。
