【摘要】 摘要:本文对低密度脂蛋白(LDL)的形成、结构做了简单概述。LDL是由极低密度脂蛋白(VLDL)演化而成,对于其结构,目前为人们普遍接受的是乳状液颗粒模型。作为LDL中的主要载脂蛋白apoB-100,其一级结构已经为人们所知,而高级结构的研究也得出了不少有益的结论。此外,本文还对LDL上受体结合部位和LDL受体上LDL结合部位等方面做了简单叙述。更多还原

【Abstract】 Structure and formation of low density lipoproteins (LDLs) were summarized. LDLs were derived from very low density lipoprotein (VLDLs). Emulsion particle model was established for LDLs. Primary sequence of apolipoprotein B-100 was well known and many conclusions have been obtained about secondary and tertiary structure of apoB-100. In addition, receptor-binding domains on LDLs and LDL-binding domains on LDL receptors were also described.更多还原
