CAS：9012-76-4
脫乙酰度≥95%,,粘度100-200 mpa.s,
分子式：C6nH11nNO4n
產(chǎn)品介紹：殼聚糖是一種線性氨基多糖,由大約20％β1,4 -連接的N -乙酰- D -氨基葡萄糖（葡萄糖胺），和大約80％的β1,4 -連接的D -氨基葡萄糖（GlcN）組成，由甲殼素在熱堿液中部分脫乙酰準(zhǔn)備而成。不溶于水，羧化殼聚糖經(jīng)羧化處理，溶于水。
用途：殼聚糖是一種具生物相容性、抗細(xì)菌和能被生物降解的聚電解質(zhì)，具有廣泛的生物醫(yī)藥和工業(yè)用途。它的化學(xué)性質(zhì)和低毒性可作為藥物的組成部分、用于基因轉(zhuǎn)移系統(tǒng)、用作生物降解膜及作為組織工程中的骨架。
備注：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.
