Pfupiso:Kazhinji kutaura, chitin inonyanya kureva chitosan, inozivikanwawo sechitosan, deacetylated chitin, deacetylated chitin, soluble chitin, uye soluble chitin.Amorphous solids, specific rotation[ α] D11—3°～+10°. Inenge isinganyungudike mumvura, asi inonyungudika muorganic acids yakadai sefomic acid, acetic acid, benzoic acid, naphthenic acid, uye dilute inorganic acids.Zvigadzirwa zvemaindasitiri zvichena kana greyish chena translucent sheet senge yakasimba ine zvishoma pearl luster.Haina kunhuhwirira, Chemicalbook haina chepfu, inoshatisa nyore, uye isingawanzo yakasikwa cationic polyelectrolyte.Polysaccharides inowanikwa nehydrolysis ine alkali yakasimba kana enzymatic hydrolysis kubvisa mapoka eacetyl kubva kuboka reshuga rechitin.Inonyungudika mu low acidity aqueous solutions, ine biocompatibility yakanaka, haina antigenicity, uye hainyungudike mumvura dzevanhu.Inowanikwa kubva kuchitin muhombodo dzemhuka dzakaderera uye zvirimwa zvinowanikwa zvakanyanya mumasikirwo, senge arthropods (shrimp, crab), kuburikidza nedeacetylation reaction nekuwedzera alkali uye kupisa.
Chiito:Pane nzira mbiri huru dzeantibacterial effect ye chitosan: imwe ndeyokuti chitosan adsorbs pamusoro pemasero kuti aite yakakwirira molecular membrane, kudzivirira kutakurwa kwezvokudya mumasero, nokudaro kutamba bacteriostatic uye bactericidal basa;Imwe nzira ndeyekuti chitosan inopinda mukati mesero muviri, ichishambadza cytoplasm ne Chemicalbook anions musero muviri, uye ichikonzera flocculation, ichikanganisa yakajairika physiological zviitiko zvesero, nekudaro kuuraya mabhakitiriya.Nekuda kwezvakasiyana madziro emadziro emadziro e gram-positive bacteria uye gram-negative bacteria, uye madhigirii akasiyana esimba rezviviri zvinokonzeresa pavari, chitosan ine huremu hwakasiyana hwemamolecular huremu hune nzira dzakasiyana dzeantibacterial.Chitosan is a dietary fiber ine mhedzisiro ye kuderedza serum cholesterol, kudzora maruva emudumbu, uye kuderedza BP.Mushure mekudya kwevanhu chitosan, kuongorora fecal kunoratidza kuti inenge isina kugayiwa uye kunyudzwa, saka ndeyechikamu chekudya fiber.
Parizvino, ZhongAn yakagadzira vanobatika nemusika weUSA, uye inoenderera mberi nekupa Chitosan kwavari mwedzi wega wega.Kana iwe uine chero chaunoda, unogona kubata ZhongAn, uye ZhongAn ichapa zvinhu zvakanakisa uye masevhisi.
