[Abstract]  Chondroitin sulfate (CS), a member of the glycosaminoglycan (GAG) family of carbohydrates, is composed of linear, sulfated repeating disaccharide sequences of N-acetyl-D-galactosamine (GalNAc) and glucuronic acid (GlcA). Recently, a keratan sulfate (KS) disaccharide [GlcNAc6S(β1-3)Galactose(β1-]-branched CS-E was identified from the clam species M. chinensis. This protocol details a methodology to analyze the glycosidic linkages of galactose in KS disaccharide-branched CS by GC-MS analysis. A complementary method for the identification and characterization of KS-branched CS in M. chinensis can be found in Higashi et al. (2016). [摘要]  硫酸软骨素(CS)是碳水化合物的糖胺聚糖(GAG)家族的成员,由N-乙酰基-D-半乳糖胺( GalNAc)和葡萄糖醛酸(GlcA)。 最近,从中华蛤中鉴定出硫酸角质素(KS)二糖[GlcNAc6S(β1-3)半乳糖(β1-) - 支化的CS-E。该方案详细描述了分析方法 通过GC-MS分析在KS二糖 - 分枝CS中的半乳糖的糖苷键。可以在Higashi等人中找到用于鉴定和表征KS-分枝CS的互补方法 (2016)。

【背景】已经显示来自多糖的部分甲基化糖醇乙酸酯(PMAA)的反应产物的气相色谱/质谱(GC-MS)分析代表了研究糖苷键的有力工具。 M的PMAAs准备。 在该方案中,根据Anumula和Tayler(1992)的方法进行小的修改。
