应用

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。

生化/生理作用

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。

包装

密封安瓿瓶

制备说明

胆固醇亚油酸在氯仿中生成澄清无色溶液，浓度为 100 mg/mL。

To test whether high-density lipoproteins (HDL) could aid in the removal in vivo of potentially atherogenic oxidized lipids, we perfused rat liver in situ with buffer supplemented with isolated human HDL containing small amounts of cholesteryl linoleate hydro(pero)xides [CH18:2-O(O)H]. Perfusion

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). When [3H]Ch18:2-OOH- and [3H]18:2-OH-labeled LDL were incubated at 37 degrees

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

Algae are becoming a strategic source of fuels, food, feedstocks, and biologically active compounds. This potential has stimulated the development of innovative analytical methods focused on these microorganisms. Algal lipids are among the most promising potential products for fuels as

Cholesteryl linoleate hydroperoxide (CLOOH) and hydroxide (CLOH) are present in human atheroma. The intracellular metabolism of low density lipoprotein (LDL)-derived CLOOH and CLOH remain undefined because extensive free radical-mediated LDL oxidation, which modifies LDL apolipoprotein B sufficiently to allow endocytosis
