Kev Txheeb Xyuas:Feem ntau hais lus, chitin feem ntau yog hais txog chitosan, uas tseem hu ua chitosan, deacetylated chitin, deacetylated chitin, soluble chitin, thiab soluble chitin. Amorphous solids, kev sib hloov tshwj xeeb [α] D11—3°～+10°. Yuav luag tsis yaj hauv dej, tab sis yaj hauv cov organic acids xws li formic acid, acetic acid, benzoic acid, naphthenic acid, thiab dilute inorganic acids. Cov khoom lag luam yog cov ntawv dawb lossis greyish dawb translucent zoo li cov khoom khov nrog me ntsis pearl luster. Tsis muaj ntxhiab, Chemicalbook tsis muaj tshuaj lom, yooj yim degradable, thiab yog ib qho tsis tshua muaj cationic polyelectrolyte ntuj. Polysaccharides tau los ntawm hydrolysis nrog alkali muaj zog lossis enzymatic hydrolysis kom tshem tawm acetyl pawg ntawm cov suab thaj pawg ntawm chitin. Nws yog soluble hauv cov kua qaub qis acidity aqueous, muaj biocompatibility zoo, tsis muaj antigenicity, thiab yog insoluble hauv tib neeg cov kua. Nws tau txais los ntawm chitin hauv lub plhaub ntawm cov tsiaj qis thiab cov nroj tsuag uas pom dav hauv xwm, xws li arthropods (cws, crab), los ntawm kev deacetylation reaction los ntawm kev ntxiv alkali thiab cua sov.
Kev Ua Haujlwm：Muaj ob txoj hauv kev tseem ceeb rau cov nyhuv antibacterial ntawm chitosan: ib qho yog tias chitosan adsorbs rau ntawm qhov chaw ntawm cov hlwb los tsim ib daim nyias nyias molecular siab, tiv thaiv kev thauj cov as-ham mus rau hauv cov hlwb, yog li ua lub luag haujlwm bacteriostatic thiab bactericidal; Lwm txoj hauv kev yog tias chitosan nkag mus rau hauv lub cev cell, adsorbing cytoplasm nrog Chemicalbook anions hauv lub cev cell, thiab ua rau flocculation, cuam tshuam cov haujlwm physiological ib txwm ntawm lub cell, yog li tua cov kab mob. Vim yog cov qauv phab ntsa cell sib txawv ntawm cov kab mob gram zoo thiab cov kab mob gram tsis zoo, thiab cov degree sib txawv ntawm kev cuam tshuam ntawm ob qho teebmeem rau lawv, chitosan nrog cov qhov hnyav molecular sib txawv muaj cov txheej txheem antibacterial sib txawv. Chitosan yog cov khoom noj khoom haus fiber uas muaj cov teebmeem ntawm kev txo cov roj cholesterol hauv cov ntshav, tswj cov kab mob hauv plab hnyuv, thiab txo cov ntshav siab. Tom qab tib neeg noj chitosan, kev tshuaj xyuas quav qhia tau hais tias nws yuav luag tsis zom thiab nqus tau, yog li nws yog ib pawg ntawm cov khoom noj khoom haus fiber.
Tam sim no, ZhongAn tau tsim kev sib cuag nrog lub khw muag khoom hauv Tebchaws Meskas, thiab txuas ntxiv muab Chitosan rau lawv txhua hli. Yog tias koj muaj kev thov, koj tuaj yeem tiv tauj ZhongAn, thiab ZhongAn yuav muab cov khoom lag luam thiab cov kev pabcuam zoo tshaj plaws.
