Hōʻuluʻulu manaʻo:Ma ke ʻano laulā, ʻo ka chitin ke kumu nui o ka chitosan, i ʻike ʻia hoʻi ʻo chitosan, deacetylated chitin, deacetylated chitin, soluble chitin, a me soluble chitin. Nā mea paʻa amorphous, rotation kikoʻī [α] D11—3°～+10°。 Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā waikawa organik e like me ka formic acid, acetic acid, benzoic acid, naphthenic acid, a me nā waikawa inorganic dilute. He keʻokeʻo a hina hina paha nā huahana ʻoihana e like me nā mea paʻa me ka ʻōlinolino momi iki. ʻAʻohe ʻala, ʻaʻohe mea ʻawahia, maʻalahi ka palaho, a he polyelectrolyte cationic kūlohelohe kakaikahi. Loaʻa nā polysaccharides ma o ka hydrolysis me ka hydrolysis alkali ikaika a i ʻole enzymatic e wehe i nā hui acetyl mai ka hui kō o chitin. Hiki ke hoʻoheheʻe ʻia i loko o nā hopena wai haʻahaʻa acidity, loaʻa ka biocompatibility maikaʻi, ʻaʻohe antigenicity, a ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā wai kanaka. Loaʻa ia mai ka chitin i loko o nā pūpū o nā holoholona haʻahaʻa a me nā mea kanu i loaʻa nui i ke ʻano, e like me nā arthropods (ʻōpae, pāpaʻi), ma o ka hopena deacetylation ma ka hoʻohui ʻana i ka alkali a me ka hoʻomehana ʻana.
Hana：ʻElua mau ʻano hana nui no ka hopena antibacterial o ka chitosan: ʻo kekahi, ʻo ia ka hoʻopili ʻana o ka chitosan ma luna o ka ʻili o nā cell e hana i kahi membrane molekala kiʻekiʻe, e pale ana i ka lawe ʻana o nā meaʻai i loko o nā cell, no laila e pāʻani ana i kahi hana bacteriostatic a me bactericidal; ʻO kekahi ʻano hana, ʻo ia ke komo ʻana o ka chitosan i loko o ke kino o ke cell, e hoʻopili ana i ka cytoplasm me nā anions Chemicalbook i loko o ke kino o ke cell, a e hana ana i ka flocculation, e hoʻopilikia ana i nā hana physiological maʻamau o ke cell, a no laila e pepehi ana i ka bacteria. Ma muli o nā ʻano like ʻole o ka paia cell o nā bacteria gram maikaʻi a me nā bacteria gram maikaʻi ʻole, a me nā kekelē like ʻole o ka mana o nā hopena ʻelua ma luna o lākou, ʻo ka chitosan me nā kaumaha molekala like ʻole he mau ʻano hana antibacterial like ʻole. ʻO Chitosan kahi fiber dietary nona nā hopena o ka hōʻemi ʻana i ka cholesterol serum, ka hoʻoponopono ʻana i ka flora ʻōpū, a me ka hoʻohaʻahaʻa ʻana i ke koko. Ma hope o ka ʻai ʻana o ke kanaka i ka chitosan, hōʻike ka nānā ʻana o ka fecal ʻaʻole ia i ʻeli ʻia a komo ʻia, no laila no kahi ʻano o ka fiber dietary.
I kēia manawa, ua hoʻokumu ʻo ZhongAn i nā pilina me ka mākeke o ʻAmelika Hui Pū ʻIa, a ke hoʻomau nei i ka hoʻolako ʻana iā Chitosan iā lākou i kēlā me kēia mahina. Inā he koi kāu, hiki iā ʻoe ke hoʻokaʻaʻike aku iā ZhongAn, a na ZhongAn e hāʻawi i nā waiwai a me nā lawelawe maikaʻi loa.
