介绍:	壳聚糖是一种线性氨基多糖,由大约20％β1,4 -连接的N -乙酰- D -氨基葡萄糖（葡萄糖胺），和大约80％的β1,4 -连接的D -氨基葡萄糖（GlcN）组成，由甲壳素在热碱液中部分脱乙酰准备而成。不溶于水，羧化壳聚糖经羧化处理，溶于水。
用途:	壳聚糖是一种具生物相容性、抗细菌和能被生物降解的聚电解质，具有广泛的生物医药和工业用途。它的化学性质和低毒性可作为药物的组成部分、用于基因转移系统、用作生物降解膜及作为组织工程中的骨架。
备注:	Prepared by the alkaline deacetylation of chitin obtained from the shells of shrimp (Pandalus borealis). Chitin is manufactured industrially by crushing shrimp shells, then washing the solids with acids to remove inorganic and proteinaceous material. The purified chitin is deacetylated to chitosan by treatment with a strong base such as sodium hydroxide. The resulting chitosan may be further purified by preparation of solutions in acid followed by neutralization and precipitation.
