Isishwankathelo:Ngokubanzi, i-chitin ibhekisa kakhulu kwi-chitosan, eyaziwa ngokuba yi-chitosan, i-chitin e-deacetylated, i-chitin e-deacetylated, i-chitin enyibilikayo, kunye ne-chitin enyibilikayo. I-Amorphous solids, i-specific rotation[α] D11—3°～+10°。 Phantse ayinyibiliki emanzini, kodwa inyibilika kwi-organic acids ezifana ne-formic acid, i-acetic acid, i-benzoic acid, i-naphthenic acid, kunye ne-dilute inorganic acids. Iimveliso zoshishino zimhlophe okanye zingwevu ezimhlophe ezikhanyayo njengezinto eziqinileyo ezine-pearl luster encinci. Ayinavumba, i-Chemicalbook ayinatyhefu, inokonakala lula, kwaye yi-polyelectrolyte yendalo engaqhelekanga ye-cationic. Ii-Polysaccharides ezifunyenwe yi-hydrolysis ene-alkali enamandla okanye i-enzymatic hydrolysis ukususa amaqela e-acetyl kwiqela leswekile le-chitin. Inyibilika kwizisombululo zamanzi ezine-acid ephantsi, ihambelana kakuhle ne-bio, ayina-antigenicity, kwaye ayinyibiliki kulwelo lwabantu. Ifunyanwa kwi-chitin kwiigobolondo zezilwanyana ezisezantsi kunye nezityalo ezifumaneka kakhulu kwindalo, njengee-arthropods (ii-shrimp, ii-crab), ngokusebenzisa i-deacetylation reaction ngokongeza i-alkali kunye nokufudumala.
Isenzo：Kukho iindlela ezimbini eziphambili zesiphumo sokulwa neentsholongwane se-chitosan: enye kukuba i-chitosan ifunxa phezu kweeseli ukuze yenze i-membrane ephezulu yeemolekyuli, ithintele ukuthuthwa kwezondlo kwiiseli, ngaloo ndlela idlala indima ye-bacteriostatic kunye ne-bactericidal; Enye indlela kukuba i-chitosan ingena emzimbeni weseli, ifunxa i-cytoplasm ngee-anions zeChemicalbook emzimbeni weseli, kwaye ibangele ukuqunjelwa, iphazamise imisebenzi eqhelekileyo ye-physiological yeseli, ngaloo ndlela ibulala iintsholongwane. Ngenxa yezakhiwo ezahlukeneyo zodonga lweseli zebhaktiriya ezinegram kunye ne-gram negative bacteria, kunye namanqanaba ahlukeneyo empembelelo yeziphumo ezimbini kuzo, i-chitosan enobunzima obahlukeneyo beemolekyuli ineendlela ezahlukeneyo zokulwa neentsholongwane. I-Chitosan yifayibha yokutya eneziphumo zokunciphisa i-cholesterol ye-serum, ukulawula izityalo zamathumbu, kunye nokunciphisa uxinzelelo lwegazi. Emva kokuginya i-chitosan ebantwini, uhlalutyo lwendle lubonisa ukuba ayigaywanga kwaye ayifunxwanga, ngoko ke ikwiqela lefayibha yokutya.
Okwangoku, iZhongAn iqalise unxibelelwano nemarike yaseMelika, kwaye iyaqhubeka nokubanika iChitosan inyanga nenyanga. Ukuba unayo nayiphi na imfuno, ungaqhagamshelana neZhongAn, kwaye iZhongAn iya kubonelela ngeempahla kunye neenkonzo ezilungileyo.
