脂蛋白 (ａ) [Ｌｉｐｏｐｒｏｔｅｉｎ(ａ)ＬＰ(ａ) ]是血浆中一种独立的脂蛋白 ,颗粒呈球状 ,表面与ＬＤＬ相似 ,其化学特性和物理性质也与ＬＤＬ相似 ,并有相同受体———载脂蛋白Ｂ10 0 (ａｐｏＢ10 0 ) ,所以曾被认为是ＬＤＬ的遗传和抗原变异型[1] 。但ＬＰ(ａ)含有α抗原
Lipoprotein (a) LP (a) is a kind of independent lipoprotein in plasma. Its surface is similar to LDL and its chemical and physical properties are similar to that of LDL. It has the same receptor --- ApoB10 0 (apoB10 0), so it has been considered as genetic and antigenic variants of LDL [1]. However, LP (a) contains an α antigen
