Dextran (MW 40000) 是一种复杂的碳水化合物聚合物，由通过糖苷键连接的葡萄糖分子组成。葡聚糖在水中具有出色的溶解性，使其可用作食品、油漆和粘合剂中的粘度调节剂或稳定剂。在生物医学领域，葡聚糖经常被用作血浆扩容剂，因为它在静脉内给药时能够增加血容量。它也可以被修改以创建基于葡聚糖的药物输送系统，例如靶向纳米颗粒。
| 生物活性 |
Dextran (MW 40000) is a complex carbohydrate polymer consisting of glucose molecules linked by glycosidic bonds. Dextran has excellent solubility in water, making it useful as a viscosity modifier or stabilizer in foods, paints and adhesives. In the biomedical field, dextran is often used as a plasma expander because of its ability to increase blood volume when administered intravenously. It can also be modified to create dextran-based drug delivery systems, such as targeted nanoparticles.
