Cov ntsiab lus: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 [α] D11-3 ° ~ + 10 °. Yuav luag insoluble hauv dej, tab sis soluble hauv 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 khib nyiab nrog me ntsis pearl luster.Tsis muaj ntxhiab tsw, Chemicalbook yog non-toxic, yooj yim degradable, thiab yog ib qho tsis tshua muaj ntuj cationic polyelectrolyte.Polysaccharides tau los ntawm hydrolysis nrog muaj zog alkali los yog enzymatic hydrolysis kom tshem tawm acetyl pawg los ntawm pawg suab thaj ntawm chitin.Nws yog soluble nyob rau hauv tsawg acidity aqueous daws, muaj biocompatibility zoo, tsis muaj antigenicity, thiab yog insoluble nyob rau hauv tib neeg kua.Nws yog tau los ntawm chitin nyob rau hauv lub plhaub ntawm cov tsiaj qis thiab cov nroj tsuag dav pom nyob rau hauv cov xwm, xws li arthropods (cws, crab), los ntawm deacetylation cov tshuaj tiv thaiv los ntawm kev ntxiv alkali thiab cua sov.
Kev ua:Muaj ob lub luag haujlwm tseem ceeb rau kev siv tshuaj tua kab mob ntawm chitosan: ib qho yog tias chitosan adsorbs rau ntawm lub hlwb kom tsim tau lub siab molecular membrane, tiv thaiv kev thauj cov as-ham rau hauv lub hlwb, yog li ua si lub luag haujlwm bacteriostatic thiab bactericidal;Lwm lub tswv yim yog tias chitosan nkag mus rau hauv lub cev ntawm tes, adsorbing lub cytoplasm nrog Chemicalbook anions hauv lub cev ntawm tes, thiab ua rau flocculation, cuam tshuam cov kev ua haujlwm ntawm lub cev ntawm tes, yog li tua cov kab mob.Vim lub cell phab ntsa sib txawv ntawm cov kab mob gram zoo thiab cov kab mob gram tsis zoo, thiab qhov sib txawv ntawm cov kev cuam tshuam ntawm ob qhov cuam tshuam rau lawv, chitosan nrog cov txheeb ze sib txawv molecular hnyav muaj cov tshuaj tiv thaiv kab mob sib txawv.Chitosan yog cov khoom noj fiber ntau uas muaj cov teebmeem ntawm txo cov roj (cholesterol) hauv cov ntshav, tswj cov hnyuv, thiab txo cov ntshav siab.Tom qab tib neeg noj chitosan, kev soj ntsuam fecal qhia tau hais tias nws yuav luag tsis zom thiab nqus, yog li nws belongs rau qeb ntawm kev noj haus fiber ntau.
Tam sim no, ZhongAn tau tsim kev sib cuag nrog Asmeskas kev lag luam, thiab tseem muab Chitosan rau lawv txhua lub hlis.Yog tias koj muaj kev thov, koj tuaj yeem tiv tauj ZhongAn, thiab ZhongAn yuav muab cov khoom zoo tshaj plaws thiab cov kev pabcuam zoo tshaj plaws.
