壳聚糖是自然界中少见的带正电荷的聚合物,经辐射降解脱乙酰化处理改性后的低分子壳聚糖,具有优良的生物相容性,无毒副作用,其代谢物也无毒,能被生物体完全吸收。水产养殖的一些研究和试验表明,低分子量壳聚糖具有促进鱼体生长的作用,但过高量的壳聚糖会明显抑制鱼的生长。在水 Chitosan is rare in nature with a positively charged polymer, modified by radiation deacetylation of low molecular weight chitosan, has excellent biocompatibility, non-toxic side effects, and its metabolites are non-toxic , Can be completely absorbed by the organism. Some aquaculture research and experiments have shown that low molecular weight chitosan can promote the growth of fish, but excessive amount of chitosan can significantly inhibit the growth of fish.
