一、壳聚糖的概念及其作用机理 1．壳聚糖的来源 甲壳素(Chitin)是法国学者于1811年在蘑菇中发现的，但当时把其误当成了纤维素；1824年，Children重复了前人的工作并发现甲壳动物残渣中含有10％左右的氮，说明该物质不是纤维素；1859年，法国学者C．Rouget将甲壳素用浓碱加热处理，得到了脱乙酰基的甲壳素，甲壳素脱乙酰基的产物即为壳聚糖(Chitosan)，其学名为(1，
First, the concept of chitosan and its mechanism of action 1. Chitin, a source of chitin, was discovered by French scholars in mushrooms in 1811, but was mistaken for cellulose at that time; in 1824, Children repeated previous work and found that crustacean residues contained 10 Nitrogen about%, indicating that the substance is not cellulose; 1859, the French scholar C. Rouget chitin with concentrated alkali heat treatment, deacetylated chitin obtained chitin deacetylation product is chitosan (Chitosan), its scientific name (1,
