目的从不同来源制备硫酸乙酰肝素(HS)，并测定其理化性质。
PurposeTo prepare heparan sulfate (HS) from different sources, and to determine their physicochemical properties.
硫酸乙酰肝素是一种结合在核心蛋白上的带负电荷的长直链多糖。
Heparan sulfates are long, unbranched, negatively charged polysaccharides that are bound to core proteins.
硫酸乙酰肝素并不是一种蛋白质，在某种程度上它只是经常参于糖基化的一种富硫的、类糖的分子。
Heparan sulphate is not a protein. It is, rather, a sulphur-rich sugar-like molecule of a sort often involved in glycosylation.
磷脂酰肌醇蛋白聚糖3是硫酸乙酰肝素糖蛋白家族中的一员，它参与调控细胞增殖、分化、黏附和迁移等过程。
As one of the members of heparan sulfate proteoglycans, Glypican-3 (GPC3) participates in the process of cell proliferation, differentiation, adhesion and migration.
目的评估一种硫酸乙酰肝素的生化学分析方法，并对小鼠肝脏硫酸乙酰肝素的二糖组成及分子量进行生化分析。
[Objective] to evaluate a biochemical analysis method for heparin sulfate and to experimentally analyze the disaccharide composition and chain length of mouse liver heparin sulfate.
硫酸乙酰肝素是肝磷脂的前体，是重要的抗凝剂，目前只能从血液中提取，从未成功合成提取过，它并不是蛋白质，而是一种富硫似糖的分子，经常参与糖基化反应。
This is a precursor to heparin, an important anti-clotting agent that has, at present, to be extracted from blood, rather than being synthesised. Heparan sulphate is not a protein.
