Soo Koobid:Guud ahaan marka la hadlo, chitin waxaa inta badan loola jeedaa chitosan, kaas oo sidoo kale loo yaqaan chitosan, chitin deacetylated, chitin deacetylated, chitin milmi kara, iyo chitin milmi kara. Adkaha aan qaab-dhismeedka lahayn, wareeg gaar ah[α] D11—3°～+10°。 Ku dhawaad aan ku milmi karin biyaha, laakiin ku milmi kara asiidhyada dabiiciga ah sida formic acid, acetic acid, benzoic acid, naphthenic acid, iyo asiidhyada aan dabiiciga ahayn ee khafiifka ah. Badeecadaha warshaduhu waa xaashi cad ama cawlan oo cad oo cad oo cad oo leh dhalaal yar oo luul ah. Ur la'aan, Chemicalbook ma aha sun, si fudud ayaa loo burburin karaa, waana polyelectrolyte dabiici ah oo naadir ah. Polysaccharides-ka laga helo hydrolysis iyadoo la isticmaalayo alkali xooggan ama hydrolysis enzymatic si looga saaro kooxaha acetyl kooxda sonkorta ee chitin. Waa milmi kara xalalka biyaha ee aashitada yar, wuxuu leeyahay iswaafajin wanaagsan oo bio ah, ma laha antigenicity, waana mid aan ku milmi karin dareeraha aadanaha. Waxaa laga helaa chitin ku jira qolofka xayawaanka hoose iyo dhirta si weyn looga helo dabeecadda, sida arthropods (shrimp, carsaanyo), iyada oo loo marayo falcelinta deacetylation iyadoo lagu darayo alkali iyo kuleyl.
Ficil:Waxaa jira laba farsamo oo ugu muhiimsan saamaynta bakteeriyada dila ee chitosan: mid waa in chitosan uu ku nuugo dusha sare ee unugyada si uu u sameeyo xuub molecular sare, taasoo ka hortagaysa gaadiidka nafaqooyinka unugyada, taasoo ka ciyaareysa door bacteriostatic iyo bakteeriya disha; Farsamo kale ayaa ah in chitosan uu galo jirka unugyada, isagoo nuugaya cytoplasm-ka iyadoo la adeegsanayo anions-ka Chemicalbook ee jirka unugyada, isla markaana keenaya flocculation, taasoo carqaladeynaysa hawlaha caadiga ah ee jirka ee unugyada, taasoo disha bakteeriyada. Sababtoo ah qaab-dhismeedka derbiga unugyada ee kala duwan ee bakteeriyada gram-positive iyo bakteeriyada gram-negative, iyo heerarka kala duwan ee saameynta labada saameynood, chitosan oo leh miisaanno molecular oo kala duwan ayaa leh habab kala duwan oo bakteeriyada dila. Chitosan waa faybar cunto oo leh saameynta yaraynta kolestaroolka serum, nidaaminta flora xiidmaha, iyo hoos u dhigista cadaadiska dhiigga. Ka dib marka aad qaadato chitosan, falanqaynta saxarada waxay muujineysaa in ku dhawaad aan la dheefshiidin oo la nuugo, sidaas darteed waxay ka tirsan tahay qayb ka mid ah fiber-ka cuntada.
Hadda, ZhongAn waxay xiriir la samaysay suuqa Mareykanka, waxayna sii waddaa inay Chitosan siiso bil kasta. Haddii aad qabto wax baahi ah, waxaad la xiriiri kartaa ZhongAn, ZhongAn-na wuxuu bixin doonaa alaabada iyo adeegyada ugu fiican.
