Application

将胆固醇亚油酸酯与胆固醇共超声制备分散液，研究其对红细胞膜胆固醇磷脂比的影响。作为 HPLC 标准品用于分析大鼠肝脏脂蛋白。

Biochem/physiol Actions

低密度脂蛋白 (LDL) 中含量最丰富的胆固醇酯。
胆固醇亚油酸是一种主要的胆固醇酯，与低密度脂蛋白的中性核心有关。受体-LDL 复合物被溶酶体摄取并水解以从酯中释放胆固醇。酸性胆固醇酯水解酶负责胆固醇酯的水解；有缺陷的酶可导致人体动脉粥样硬化病变的形成。

We have previously reported the detection of cholesteryl ester hydroperoxides, consisting mainly of cholesteryl linoleate hydroperoxides (Ch18:2-OOH), at nm levels in plasma from healthy humans (Y. Yamamoto and E. Niki, 1989. Biochem. Biophys. Res. Commun. 165: 988-993). To elucidate their

Cholesteryl ester hydroperoxide (CE-OOH) and phosphatidylcholine hydroperoxide (PC-OOH) are the major primary oxidation products of lipoproteins. CE-OOH is present in human and rat plasmas while PC-OOH is undetectable. This is likely due to the enzymatic (plasma glutathione peroxidase) and the

This study examines the cholesteryl ester transfer protein (CETP)-mediated exchange of cholesteryl linoleate hydroperoxide (Ch18:2-OOH) and cholesteryl linoleate hydroxide (Ch18:2-OH) between low density lipoprotein (LDL) and high density lipoprotein (HDL).
