一般描述
葡聚糖（分子量150,000）属于中性多糖类家族， 它是糖加工和其他食品生产行业中的污染物。这些糖由不同长度的α-(1-6) 糖苷键连接的D-葡萄糖单元所组成。它们以细菌胞外多糖的形式存在于细菌中，据报道是由蔗糖通过有益乳酸菌（如肠膜明串珠菌 和短乳杆菌）合成。它们可加入焙烤制品中以改善面包心质构、柔软度和面包体积，另外还可作为稳定剂和添加剂用于糖果、风味提取物、结冰组合物、饮料（包括软饮料、牛奶等）。
应用
- 创伤愈合水凝胶：研究发现胶原蛋白-聚氨酯-葡聚糖水凝胶可以通过减轻炎症和促进胶原蛋白原纤维生成，来促进创伤愈合，研究重点介绍了葡聚糖在构建用于医学应用的先进生物材料中的用途（Aguayo-Morales et al., 2024）。
- 药物递送系统：一项靶向治疗用新型葡聚糖生物偶联物（bioconjugate）的研究考察了其在增进反义寡核苷酸细胞摄取的作用，显示了葡聚糖在更高效药物递送系统开发中的关键功能（Kohashi et al., 2024）。
