Soo koobid:Guud ahaan, chitin inta badan waxa loola jeedaa chitosan, oo sidoo kale loo yaqaan chitosan, chitin deacetylated, chitin deacetylated, chitin milmaya, iyo chitin milmi.Amorphous adag, wareeg gaar ah[α] D11—3°～+10°. Ku dhawaad biyo kuma milmi karaan, laakiin ku milma asiidhyada organic sida formic acid, acetic acid, benzoic acid, naphthenic acid, iyo milic acids inorganic.Badeecadaha warshaduhu waa xaashi caddaan ah oo toosan oo cad ama cawlan sida adkaha leh dhalaal yar oo luul ah.ur-la'aan, Kiimikada Buuggu maaha mid sun ah, si fududna loo dumin karo, waana polyelectrolyte dabiici ah oo naadir ah.Polysaccharides oo lagu helay hydrolysis leh alkali xooggan ama hydrolysis enzymatic si looga saaro kooxaha acetyl ee kooxda sonkorta ee chitin.Waxay ku milmi kartaa xalal aashito ah oo hooseeya, waxay leedahay biocompatibility wanaagsan, ma laha antigenicity, waana mid aan milmi karin dareerayaasha bini'aadamka.Waxaa laga helaa chitin qolofyada xayawaanka hoose iyo dhirta si weyn looga helo dabeecadda, sida arthropods (shrimp, crab), iyada oo loo marayo falcelinta deacetylation iyadoo lagu darayo alkali iyo kuleyl.
Ficil：Waxaa jira laba hab oo waaweyn oo loogu talagalay saameynta bakteeriyada chitosan: mid waa in chitosan ay ku dhejiso dusha sare ee unugyada si ay u sameeyaan xuub sare oo kelli ah, oo ka hortagaya in nafaqooyinka la geeyo unugyada, sidaas darteedna waxay ciyaaraan door bacteriostatic iyo bakteeriyada;Hab kale ayaa ah in chitosan ay soo gasho jidhka unugyada, iyada oo cytoplasmka ku dhejisa cytoplasmka anions Kiimikada ee ku jira jidhka unugyada, oo keenta qulqulo, khalkhal galiyaan dhaqdhaqaaqa jireed ee caadiga ah ee unugga, taas oo dila bakteeriyada.Sababo la xiriira qaab-dhismeedka derbiga unugga ee kala duwan ee bakteeriyada garaam positive-ka ah iyo bakteeriyada garaam negative, iyo heerka kala duwan ee saamaynta ay labada saamaynta on iyaga, chitosan oo leh miisaanno qaraabo ah oo kala duwan ayaa leh hababka bakteeriyada kala duwan. yaraynta kolestaroolka serum, nidaaminta flora mindhicirka, iyo hoos u dhigista cadaadiska dhiigga.Ka dib markii bini'aadamka la seexdo chitosan, falanqaynta saxarada ayaa muujinaysa in ay ku dhowdahay in aan la dheefshiido oo la nuugo, sidaas darteed waxay ka tirsan tahay qayb ka mid ah fiber-ka cuntada.
Waqtigan xaadirka ah, ZhongAn wuxuu xiriir la sameeyay suuqa Mareykanka, wuxuuna sii wadaa inuu siiyo Chitosan iyaga bil kasta.Haddii aad qabto wax baahi ah, waxaad la xiriiri kartaa ZhongAn, ZhongAn wuxuu ku siin doonaa alaabta iyo adeegyada ugu fiican.
