Accompanying the decrease in serum cholesterol and increase in concentration of ubiquinone in liver and its microsomes, the activity, but not the protein, of HMG-CoA reductase decreased in ubiquinone-supplemented rats. A soluble 58-kDa preparation of HMG-CoA reductase was partially inhibited on addition of ubiquinone indicating a possible feedback type of action.
伴随着血清胆固醇的降低以及肝脏及其微粒体中泛醌浓度的增加，在补充泛醌的大鼠中，HMG-CoA还原酶的活性降低，但蛋白质含量未变。添加泛醌后，一种58 kDa的可溶性HMG-CoA还原酶制剂受到部分抑制，这表明可能存在反馈作用类型。
