血浆中脂类(以下简称血脂)包括胆固醇及其酯、磷脂、甘油三酯、游离脂肪酸等,它们和载脂蛋白一起组成了各种脂蛋白。1 血浆脂蛋白的分类按照不同分析方法,血浆脂蛋白分类命名不同,例如采用电泳法,根据脂蛋白电泳分为α、前β、β和乳糜微粒(CM)四种;采用超速离心法,根据密度高低分为高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、极低密度脂蛋 Plasma lipids (hereinafter referred to as blood lipids) include cholesterol and its esters, phospholipids, triglycerides, free fatty acids, which together with apolipoproteins make up a variety of lipoproteins. 1 Classification of plasma lipoproteins According to different analysis methods, the classification of plasma lipoproteins is different, for example, electrophoresis, according to lipoprotein electrophoresis is divided into α, β, β and chylomicrons (CM) four; ultracentrifugation, according to The density is divided into high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein
