Abstract
The enzymic activities NADH-ubiquinone reductase, succinate-ubiquinone reductase and ubiquinol oxidase were evaluated in beef heart mitochondria in presence of short ubiquinone homologs. Preliminar data obtained indicate that short chain homologs, less lipophilic than natural ubiquinone do not reach the reoxidation site in absence of endogenous ubiquinone.
摘要
在存在短链泛醌同系物的情况下，对牛心线粒体中的NADH-泛醌还原酶、琥珀酸-泛醌还原酶和泛醇氧化酶的酶活性进行了评估。获得的初步数据表明，与天然泛醌相比亲脂性较低的短链同系物，在没有内源性泛醌的情况下无法到达再氧化位点。
