Pfupiso:Kazhinji, 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 mu organic acids dzakadai se formic acid, acetic acid, benzoic acid, naphthenic acid, uye inonyungudutsa inorganic acids. Zvigadzirwa zvemaindasitiri zvichena kana kuti grey chena translucent sheet senge solids dzine light pearl luster. Chemicalbook haina hwema, haina chepfu, inoora nyore nyore, uye i polyelectrolyte isingawanzoitiki yechisikigo. Polysaccharides inowanikwa ne hydrolysis ine alkali yakasimba kana enzymatic hydrolysis kubvisa mapoka eacetyl kubva muboka reshuga re chitin. Inonyungudika mu low acidity aqueous solutions, ine biocompatibility yakanaka, haina antigenicity, uye hainyungudike mumvura yevanhu. Inowanikwa kubva kuchitin mumagoko emhuka dzakaderera nemiti inowanikwa zvakanyanya muzvisikwa, senge arthropods (shrimp, crab), kuburikidza ne deacetylation reaction nekuwedzera alkali nekupisa.
Chiito：Kune nzira mbiri huru dzekuita kuti chitosan ikwanise kurwisa mabhakitiriya: imwe ndeyekuti chitosan inonyudza pamusoro pemasero kuti igadzire membrane yakakura yemamorekuru, ichidzivirira kutakurwa kwezvinovaka muviri mumasero, nokudaro ichiita basa rebhakitiriya uye rekuuraya mabhakitiriya; Imwe nzira ndeyekuti chitosan inopinda mumuviri wesero, ichinyudza cytoplasm neChemicalbook anions mumuviri wesero, uye ichikonzera kutenderera, ichikanganisa mashandiro emuviri wesero, nokudaro ichiuraya mabhakitiriya. Nekuda kwemaumbirwo akasiyana emadziro esero emabhakitiriya ane gram-positive nemabhakitiriya ane gram-negative, uye mwero wakasiyana wepesvedzero yemhedzisiro yacho paari, chitosan ine huremu hwakasiyana hwemamorekuru ine nzira dzakasiyana dzekurwisa mabhakitiriya. Chitosan ifiber yekudya ine mhedzisiro yekuderedza cholesterol muropa, kudzora maruva emudumbu, uye kuderedza BP. Mushure mekumedzwa kwechitosan nevanhu, ongororo yetsvina inoratidza kuti inenge isina kugayiwa uye kunyudzwa, saka iri muchikamu chefiber yekudya.
Parizvino, ZhongAn yave nehukama nemusika weUSA, uye iri kuramba ichipa Chitosan kwavari mwedzi wega wega. Kana paine chaunoda, unogona kubata ZhongAn, uye ZhongAn ichapa zvinhu nemasevhisi akanakisa.
