一般描述

葡聚糖是D-吡喃葡萄糖的细菌胞外多糖。它由主链的α-（1→6）键组成，还有数量不定的α-(1→2)、α-(1→3)、 α-(1→4) 支链键。来自 肠膜明串珠菌 B512F 的葡聚糖包含 95%的α- (1→6) 键和5%的 α-（1→3）支链键。来自 肠膜明串珠菌1299的不可溶葡聚糖 包含 63%的 α-（1→6）、 27%的 α-(1→2) 和 8% 的α-（1→3）键。

应用

将右旋糖酐用作长的亲水性间隔臂提高了作用于大分子的固定化蛋白质的性能。
来自肠膜明串珠菌的葡聚糖可用于：
  • 重悬丸剂和制备′ 平衡盐溶液（HBSS）用于分离冷冻死后脑组织的 血管核（vascular nuclei）
  • 制备溶于磷酸缓冲盐溶液的葡聚糖溶液，维持角膜水分并使角膜厚度恢复为人眼的生理水平
  • 作为通过溶菌酶聚乙二醇化反应制备的原位双水相系统（ATPS）制剂中的聚合物溶液

生化/生理作用

葡聚糖是一种市售药物，特别是用作血浆增量剂。这种细菌多糖有多种应用，如食品、药物和化学品行业中的助剂、增稠剂、载体和稳定剂。葡聚糖在食品行业可用于果酱和冰淇淋的增稠。 它可防止糖结晶并截留水分。 这有助于保留多种食物的风味和外观。

Corneal biomechanics is an essential parameter for developing diagnostic and treatment methods of corneal-related diseases. It is widely accepted that corneal mechanical strength stems from the stroma's collagenous composition. However, more comprehensive insight into the mechanical properties within the stroma
