Hōʻuluʻulu manaʻo:Ma ka ʻōlelo maʻamau, pili ka chitin i ka chitosan, ka mea i ʻike ʻia he chitosan, deacetylated chitin, deacetylated chitin, soluble chitin, a me soluble chitin.ʻO nā mea paʻa amorphous, ka hoʻololi kikoʻī [α] D11—3°～+10°。 Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika organik e like me formic acid, acetic acid, benzoic acid, naphthenic acid, a dilute inorganic acids.He keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo e like me nā mea paʻa me kahi momi liʻiliʻi.ʻAʻala ʻole, ʻaʻohe mea ʻawaʻawa ʻo Chemicalbook, hiki ke hoʻohaʻahaʻa ʻia, a he polyelectrolyte cationic kūlohelohe maoli.ʻO nā polysaccharides i loaʻa ma ka hydrolysis me ka alkali ikaika a i ʻole ka hydrolysis enzymatic e wehe i nā pūʻulu acetyl mai ka hui kō o chitin.Hiki ke hoʻoheheʻe ʻia i loko o nā wai wai wai haʻahaʻa, he biocompatibility maikaʻi, ʻaʻohe antigenicity, a hiki ʻole 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 ʻike nui ʻia ma ke ʻano, e like me nā arthropods (shrimp, crab), ma o ka deacetylation reaction ma ka hoʻohui ʻana i ka alkali a me ka hoʻomehana.
Hana：ʻElua mau hana nui no ka hopena antibacterial o chitosan: ʻo ka chitosan adsorbs ma luna o ka ʻili o nā cell e hana i kahi membrane molecular kiʻekiʻe, e pale ana i ka lawe ʻana i nā meaʻai i loko o nā cell, a laila e pāʻani ana i kahi hana bacteriostatic a me bactericidal;ʻO kekahi hana ʻē aʻe ke komo ʻana o ka chitosan i loko o ke kino o ka cell, adsorbing i ka cytoplasm me ka Chemicalbook anions i loko o ke kino cell, a hoʻoulu i ka flocculation, hoʻopau i nā hana physiological maʻamau o ka cell, a laila pepehi i ka bacteria.Ma muli o nā ʻano like ʻole o ka pā hale o ka gram positive bacteria a me ka gram negative bacteria, a me nā pae like ʻole o ka hopena o nā hopena ʻelua ma luna o lākou, ʻo ka chitosan me nā paona molekika pili like ʻole he mau hana antibacterial like ʻole. hoʻemi i ka cholesterol serum, hoʻoponopono i ka flora intestinal, a hoʻohaʻahaʻa i ke koko.Ma hope o ka ʻai ʻana o ke kanaka i ka chitosan, hōʻike ka fecal analysis i ka aneane ʻaʻole i hoʻoheheʻe ʻia a hoʻopaʻa ʻia, no laila aia ia i kahi ʻano o ka fiber dietary.
I kēia manawa, ua hoʻokumu ʻo ZhongAn i nā pilina me ka mākeke USA, a hoʻomau i ka hāʻawi ʻana iā Chitosan iā lākou i kēlā me kēia mahina.Inā he koi kāu, hiki iā ʻoe ke hoʻokaʻaʻike iā ZhongAn, a na ZhongAn e hāʻawi i nā waiwai a me nā lawelawe maikaʻi loa.
