【摘要】：正壳聚糖是自然界唯一的碱性多糖,具有生物相容性、可降解等功能活性,日益受到人们的关注和青睐,在食品、化工、纺织、医药、环保等领域都有着广泛的用途[1-2]。壳聚糖属于高聚物,自然界中天然存在的壳聚糖相对分子质量一般在几万至上百万不等,经过化学方法改性的壳聚糖的相对分子质量一般范围很宽[3-4],文献报道的壳聚糖相对分子质量范围为5.0×102~1.0×106,且相对分子质量及其分
[Abstract]:Chitosan is the only alkaline polysaccharide in nature, with biocompatibility, biodegradability and other functional activities, increasingly attracted attention and favor, in food, chemical, textile, medicine, environmental protection and other fields have a wide range of applications [1-2]. Chitosan is a kind of polymer. The relative molecular weight of natural chitosan varies from tens of thousands to millions. The relative molecular weight of chitosan modified by chemical method is very wide [3-4]. The reported relative molecular weight range of chitosan is 5.0 脳 102N 1.0 脳 106, and the relative molecular weight and its components are also very wide.
