一般描述

葡聚糖是乳酸菌利用蔗糖合成的胞外多糖。它由重复的 D-葡萄糖单元构成,单体间通过 α-1,6糖苷键连接。此外,线性 D-葡萄糖链常间断出现分支结构,这些分支由 α-1,4, α-1,3,或 α-1,2糖苷键连接。

应用

本分析标准品也可适用于以下情况:
  • 基于高效体积排除色谱(HPSEC)测定从菠萝发酵物中提取的 柠檬明串珠菌 B-2合成的葡聚糖分子量
  • 用搭配水溶性凝胶柱的高效液相色谱测定从四种 木耳 中提取的多糖的分子量
  • 用凝胶渗透色谱(GPC)鉴定从 青钱柳 干叶经阴离子交换色谱分离的水溶性多糖的分子量
  • 基于凝胶渗透色谱(GPC)测定两种 肠膜明串珠菌产生的葡聚糖的分子量
  • 用高效体积排除色谱(HPSEC)评估果树修剪期修剪掉的小苹果中的水溶性多糖的分子量。
