生物渗透

The molar ratio of sulfate ions to carboxylate ions is determined by conductometric titration method and the molecular weight is tested by high performance gel permeation chromatography. The precision of these two methods is also studied. To improve the detection sensitivity, guanidine hydrochloride is used as the best derivation reagent of 911. A systematic research is done on the optimum derivatization condition of 911 and Guanidine hydrochloride. The M /G ratio of 911 has direct relation to its biological activity.

论文首先对911的基本理化性质进行了系统的分析，以电导滴定法和高效凝胶渗透色谱法分别测定了分子中硫酸根羧酸根的比值和911的分子量，并探讨了两种分析方法的精密度。911分子没有紫外吸收，为提高检测灵敏度，本文采用荧光标记法，通过对三种荧光试剂与几种寡糖和多糖衍生效果的综合比较，最终确定了盐酸胍为最佳衍生试剂，并以911为代表详细探讨了衍生化反应的最优条件。911糖链结构与褐藻胶主链结构类似，以甘露糖醛酸和古罗糖醛酸的嵌段形式存在，分子中M/G比值与911的物理化学性质和生物活性有直接关系。
