新生的极低密度脂蛋白(VLDL)颗粒赖以装配并继而定向通过分泌囊泡,这种多细胞器的通路穿梭至胞外的分子向相互作用尚不明了。载脂蛋白B(ApoB)至少以两种类型存在。一些实验结果提示,VLDL的装配需要一种或二种分子量类型的ApoB。但是由于在研究ApoB方面的技术上的问题,诸如自身相联以及水溶液中不能维持其溶解性等原因,故对其结构、顺序以及化学组成所知甚少,而且限于不充分的化学资料,对于ApoB指导VLDL装配和分泌的独特的分子特性仍不清楚。 Newborn very low density lipoprotein (VLDL) particles relied on to assemble and, in turn, direct secretion through the vesicles, and the molecular orbital shuttle of this organelle to the extracellular molecules is not yet known. Apolipoprotein B (ApoB) is present in at least two types. Some experimental results suggest that VLDL assembly requires one or two molecular weight ApoBs. However, little is known about the structure, sequence, and chemical composition of the ApoBs due to their technical problems such as their own association with each other and their inability to maintain their solubility in aqueous solutions, and is limited to inadequate chemical data, The unique molecular characteristics that ApoB directs VLDL assembly and secretion remain unclear.
