一般說明

葡聚糖是 D-吡喃葡萄糖的一种细胞外细菌聚合物。它主要包括主链中的α-(1→6)个连接和可变数量的 α-(1→2)，α-(1→3)，α-(1→4)个支链连接。
葡聚糖是由线性α(1→6)连接的葡萄糖单元和α(1→3)连接启动的支链组成的支链葡聚糖。葡聚糖的分子量范围为10,000至150,000 Kd。葡聚糖在许多应用中被用作血容量扩张剂、稳定剂、基质组分、结合平台、润滑剂和物理结构组分。由于低分子量的葡聚糖具有不同的粘度、聚集性和渗透性能，因此通常比高分子量的葡聚糖更受欢迎。

應用

来自明串珠菌属的葡聚糖已用于：
  • 酪蛋白酸的糖基化研究与葡萄糖相比碳水化合物链长度增加的影响
  • 用于基质辅助激光解吸电离飞行时间质谱（MALDI-TOF）的质量校准，用于银纳米颗粒（AgNP）的表征
  • 作为一种无毒稳定剂，用于评估三氧化钨（WO3）纳米颗粒的体内给药

生化／生理作用

葡聚糖被用作一种药物，特别是作为一种血浆体积膨胀剂。它在食品、制药和化学工业中也可用作佐剂、乳化剂、载体和稳定剂。Sephadex 是一种交联葡聚糖，通常用于蛋白质的分离和纯化。在食品工业中，右旋糖酐可作为果酱和冰淇淋的增稠剂。它阻碍了糖结晶，并增强了水分保持。这样可以保留几种食物的味道和外观。
