一、前言 脂蛋白受体属生物膜的糖蛋白,它具有特异识别脂蛋白的功能。血浆脂蛋白经过一系列酶的降解作用,它们的载脂蛋白和脂类在脂蛋白间交换和转移,最后形成的残粒和低密度脂蛋白等,主要通过与细胞脂蛋白受体结合在细胞内进行分解代谢,才能从血浆中清除。脂蛋白进入细胞分解后的胆同醇可供重组膜的需要,或以胆固醇酯的形式储存或转运其他组织,在肝脏胆固醇可转变成胆酸盐进入肝胆循环排出体外,在肾上腺或生殖腺可供合成类固醇激 I. Introduction Lipoprotein receptor is a biofilm glycoprotein that has the function of specifically recognizing lipoproteins. Plasma lipoproteins through a series of enzyme degradation, their apolipoproteins and lipids in lipoprotein exchange and transfer, the final formation of residual particles and low-density lipoprotein, etc., mainly through the combination of lipoprotein receptors in cells Within the catabolism, can be removed from the plasma. Lipoprotein into the cells after the decomposition of bile alcohol can be used for recombinant membrane needs, or in the form of cholesteryl ester storage or transport of other tissues in the liver cholesterol can be converted into bile salts into the liver and gallbladder circulation excreted in the adrenal or gonadal available Synthesis of steroid shock
