Chidule:Nthawi zambiri, chitin amatanthauza chitosan, chomwe chimatchedwanso chitosan, deacetylated chitin, deacetylated chitin, soluble chitin, ndi soluble chitin.Zolimba za amorphous, zozungulira zenizeni[ α] D11—3°～+10°. Pafupifupi zosasungunuka m’madzi, koma zimasungunuka mu ma organic acid monga formic acid, acetic acid, benzoic acid, naphthenic acid, ndi kuchepetsa ma inorganic acid.Zogulitsa zamafakitale zimakhala zoyera kapena zotuwa zoyera ngati zolimba zowala pang'ono.Yopanda fungo, Chemicalbook ndi yopanda poizoni, imatha kuwonongeka mosavuta, ndipo ndi osowa zachilengedwe cationic polyelectrolyte.Ma polysaccharides opangidwa ndi hydrolysis okhala ndi alkali wamphamvu kapena enzymatic hydrolysis kuchotsa magulu a acetyl ku gulu la shuga la chitin.Amasungunuka mumadzi otsika a acidity, ali ndi biocompatibility yabwino, alibe antigenicity, ndipo samasungunuka m'madzi amunthu.Amapezeka kuchokera ku chitin mu zipolopolo za nyama zotsika ndi zomera zomwe zimapezeka kwambiri m'chilengedwe, monga arthropods (shrimp, nkhanu), kupyolera mu deacetylation reaction powonjezera alkali ndi kutentha.
Zochita:Pali njira ziwiri zazikulu za antibacterial zotsatira za chitosan: imodzi ndikuti chitosan adsorbs pamwamba pa maselo kuti apange nembanemba yapamwamba ya maselo, kuteteza kunyamula zakudya m'maselo, potero kusewera ndi bacteriostatic ndi bactericidal;Njira ina ndi yakuti chitosan imalowa m'thupi la selo, kutulutsa cytoplasm ndi Chemicalbook anions mu selo, ndikuyambitsa kugwedezeka, kusokoneza zochitika zachibadwa za selo, motero kupha mabakiteriya.Chifukwa cha mitundu yosiyanasiyana ya ma cell a mabakiteriya a gram-positive ndi mabakiteriya a gram-negative, komanso kusiyana kosiyana kwa zotsatira ziwiri pa iwo, chitosan chokhala ndi zolemera zosiyana za maselo zimakhala ndi njira zosiyana za antibacterial.Chitosan ndi fiber fiber yomwe ili ndi zotsatira amachepetsa cholesterol m'magazi, amawongolera matumbo, komanso amachepetsa kuthamanga kwa magazi.Anthu atamwa chitosan, kuwunika kwa ndowe kumawonetsa kuti pafupifupi sikugayidwa ndikuyamwa, chifukwa chake ndi m'gulu lazakudya.
Pakadali pano, ZhongAn yakhazikitsa kulumikizana ndi msika waku USA, ndipo ikupitilizabe kuwapatsa Chitosan mwezi uliwonse.Ngati muli ndi zomwe mukufuna, mutha kulumikizana ndi ZhongAn, ndipo ZhongAn ikupatsani katundu ndi ntchito zabwino kwambiri.
