Isifinyezo:Ngokuvamile, i-chitin ibhekisela ikakhulukazi ku-chitosan, eyaziwa nangokuthi i-chitosan, i-deacetylated chitin, i-deacetylated chitin, i-soluble chitin, ne-chitin encibilikayo.Okuqinile kwe-amorphous, ukuzungezisa okuthile[ α] D11—3°～+10°. Cishe ayincibiliki emanzini, kodwa incibilika kuma-asidi ephilayo njenge-formic acid, i-acetic acid, i-benzoic acid, i-naphthenic acid, kanye ne-dilute inorganic acid.Imikhiqizo yezimboni iyishidi elikhanyayo elimhlophe noma elimpunga elifana nezinto eziqinile ezinokucwebezela kweparele elincane.Ayinaphunga, i-Chemicalbook ayinabo ubuthi, yonakala kalula, futhi iyivelakancane ye-cationic polyelectrolyte yemvelo.Ama-polysaccharides atholwe nge-hydrolysis ene-alkali eqinile noma i-enzymatic hydrolysis ukuze kususwe amaqembu e-acetyl eqenjini likashukela le-chitin.Incibilika ezixazululweni ezinamanzi ane-asidi ephansi, inokuvumelana okuhle kwe-biocompatibility, ayinakho i-antigenicity, futhi ayincibiliki oketshezini lwabantu.Itholakala ku-chitin emagobolondweni ezilwane eziphansi nezitshalo ezitholakala kakhulu emvelweni, njengama-arthropods (izimfanzi, inkalankala), ngokusabela kwe-deacetylation ngokungeza i-alkali nokufudumala.
Isenzo:Kunezindlela ezimbili eziyinhloko zomphumela we-antibacterial we-chitosan: enye iwukuthi i-chitosan adsorbs phezu kwamangqamuzana ukuze enze ulwelwesi lwamangqamuzana aphezulu, luvimbele ukuthuthwa kwezakhi kumaseli, ngaleyo ndlela kudlala indima ye-bacteriostatic ne-bactericidal;Enye indlela ukuthi i-chitosan ingena emzimbeni weseli, ikhangise i-cytoplasm nge-Chemicalbook anions emzimbeni weseli, futhi ibangele ukugeleza, iphazamise imisebenzi evamile yomzimba yengqamuzana, ngaleyo ndlela ibulale amagciwane.Ngenxa yezinhlaka ezihlukene zodonga lwamangqamuzana amagciwane e-gram-negative kanye nama-bacterium e-gram negative, kanye namazinga ahlukene ethonya lemiphumela emibili kuzo, i-chitosan enesisindo esihlukile samangqamuzana inezinqubo ezihlukene zokulwa namagciwane.I-Chitosan iyi-fiber yokudla enemiphumela yehlisa i-serum cholesterol, ilawula amathumbu amathumbu, futhi yehlise umfutho wegazi.Ngemva kokumunca umuntu i-chitosan, ukuhlaziywa kwe-fecal kubonisa ukuthi cishe ayigayiwe futhi imuncwe, ngakho iyingxenye yesigaba se-fiber yokudla.
Njengamanje, uZhongAn usesungule othintana nabo nemakethe yase-USA, futhi uyaqhubeka nokubanikeza iChitosan nyanga zonke.Uma unesidingo, ungaxhumana no-ZhongAn, futhi i-ZhongAn izohlinzeka ngezimpahla namasevisi angcono kakhulu.
