血浆蛋白质的种类很多,除极少数外,大多数蛋白质都含有糖(表1)。含糖量较多,而且糖与多肽链以共价键结合的蛋白质称为糖蛋白。电泳时,糖蛋白主要集中于α-和β-球蛋白区域。糖和蛋白质结合的方式有两种:一种是 O-糖苷键连接糖链,即肽键中的丝氨酸或苏氨酸羟基与乙酰氨基半乳糖或 There are many types of plasma proteins, with the exception of very few, most proteins contain sugars (Table 1). More sugar content, and sugar and polypeptide chain covalent bond protein called glycoprotein. During electrophoresis, glycoproteins are mainly concentrated in the α- and β-globulin regions. Sugar and protein binding in two ways: one is O-glycosidic bond-linked sugar chain, that peptide bonds in the serine or threonine hydroxy and acetyl galactosamine or
