载脂蛋白(apolipoproteins)是70年代以来从人血浆中陆续分离纯化出来的一类结合和转运脂质的特殊蛋白质,迄今发现有18种之多。按1972年Alaupovic 建议的命名法命名,主要的有载脂蛋白(apo)A1、A11、AⅣ、B100、B48、C1,C11、C111、E 及D 等10种(表1),其一级结构均已确定。近年来研究发现,载脂蛋白具有结合转运脂 Apolipoproteins are a group of special proteins that bind and transport lipids isolated and purified from human plasma since the 1970s. So far, 18 species have been found. According to the nomenclature proposed by Alaupovic in 1972, there are 10 kinds of apo A1, A11, AIV, B100, B48, C1, C11, C111, E and D (Table 1) Have been identified. In recent years, studies have found that apolipoprotein has a combination of transport fat
