Chidule:Kawirikawiri, chitin makamaka imatanthauza chitosan, yomwe imadziwikanso kuti chitosan, deacetylated chitin, deacetylated chitin, soluble chitin, ndi soluble chitin. Amorphous solids, specific rotation[α] D11—3°～+10°。 Siisungunuka m'madzi, koma imasungunuka mu organic acids monga formic acid, acetic acid, benzoic acid, naphthenic acid, ndi dilute inorganic acids. Zogulitsa zamafakitale ndi zoyera kapena zoyera zowala ngati pepala loyera lowala ndi kuwala pang'ono kwa ngale. Zopanda fungo, Chemicalbook si poizoni, zimawonongeka mosavuta, ndipo ndi polyelectrolyte yachilengedwe yosowa kwambiri. Ma polysaccharides omwe amapezeka ndi hydrolysis yokhala ndi alkali kapena enzymatic hydrolysis yolimba kuti achotse magulu a acetyl kuchokera ku gulu la shuga la chitin. Imasungunuka mu mayankho amadzi otsika acidity, imakhala ndi biocompatibility yabwino, ilibe antigenicity, ndipo sisungunuka m'madzi a anthu. Imapezeka kuchokera ku chitin m'zipolopolo za nyama zotsika ndi zomera zomwe zimapezeka kwambiri m'chilengedwe, monga arthropods (shrimp, crab), kudzera mu deacetylation reaction powonjezera alkali ndi kutentha.
Zochita：Pali njira ziwiri zazikulu zomwe chitosan imagwirira ntchito polimbana ndi mabakiteriya: imodzi ndi yakuti chitosan imalowa m'thupi la selo kuti ipange nembanemba yayikulu ya mamolekyu, kuletsa kunyamula michere kupita ku maselo, motero imagwira ntchito yolimbana ndi mabakiteriya komanso yopha tizilombo toyambitsa matenda; Njira ina ndi yakuti chitosan imalowa m'thupi la selo, kulowetsa cytoplasm ndi ma Chemicalbook anions m'thupi la selo, ndikuyambitsa kugwedezeka, kusokoneza ntchito zachibadwa za selo, motero kupha mabakiteriya. Chifukwa cha kapangidwe ka makoma osiyanasiyana a mabakiteriya a gramu-positive ndi mabakiteriya a gramu-negative, komanso kuchuluka kwa mphamvu ya zotsatira ziwirizi pa iwo, chitosan yokhala ndi kulemera kosiyanasiyana kwa mamolekyulu ili ndi njira zosiyanasiyana zotsutsana ndi mabakiteriya. Chitosan ndi ulusi wazakudya womwe umachepetsa cholesterol m'magazi, kuwongolera zomera zam'mimba, komanso kuchepetsa kuthamanga kwa magazi. Munthu akameza chitosan, kusanthula ndowe kumasonyeza kuti sichimagayidwa ndi kuyamwa, kotero chili m'gulu la ulusi wazakudya.
Pakadali pano, ZhongAn yakhazikitsa ubale ndi msika waku USA, ndipo ikupitilizabe kupereka Chitosan kwa iwo mwezi uliwonse. Ngati mukufuna, mutha kulumikizana ndi ZhongAn, ndipo ZhongAn ipereka katundu ndi ntchito zabwino kwambiri.
