Chitosan hmoov | 9012-76-4 ib

Chitosan yog cov khoom ntawm N-deacetylation ntawm chitin. Chitin (chitin), chitosan, thiab cellulose muaj cov qauv tshuaj zoo sib xws. Cellulose yog ib pawg hydroxyl ntawm C2 txoj haujlwm. Chitin, Chitosan yog hloov los ntawm ib pawg acetylamino thiab ib pawg amino ntawm C2 txoj hauj lwm, feem.

Chitin thiab chitosan muaj ntau yam khoom tshwj xeeb xws li biodegradability, cell affinity, thiab lom cov teebmeem, tshwj xeeb tshaj yog chitosan uas muaj cov amino pawg dawb. , tsuas yog alkaline polysaccharide hauv ntuj polysaccharides.

Cov amino pawg nyob rau hauv cov qauv molecular ntawm chitosan yog ntau reactive tshaj li acetylamino pawg nyob rau hauv chitin molecule, uas ua rau cov polysaccharide muaj zoo heev lom zog thiab muaj peev xwm ua tau cov tshuaj hloov kho tshuaj.

Yog li ntawd, chitosan yog suav hais tias yog ib qho kev ua haujlwm biomaterial nrog cov ntawv thov ntau dua li cov cellulose.

Chitosan yog cov khoom ntawm ntuj polysaccharide chitin tshem tawm ib feem ntawm pawg acetyl. Nws muaj ntau yam kev ua haujlwm ntawm lub cev xws li biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-txo, thiab kev tiv thaiv kab mob.

Nws yog dav siv hauv cov khoom noj. Cov khoom siv ntxiv, textiles, kev ua liaj ua teb, kev tiv thaiv ib puag ncig, kev saib xyuas kev zoo nkauj, tshuaj pleev ib ce, tshuaj tua kab mob, kev kho mob fibers, kev hnav khaub ncaws kho mob, cov ntaub so ntswg dag, tshuaj tiv thaiv-tso cov ntaub ntawv, cov noob hloov pauv, biomedical fields, kho mob absorbable cov ntaub ntawv, cov ntaub so ntswg engineering carrier cov ntaub ntawv, Kev kho mob thiab kev tsim kho tshuaj thiab ntau yam kev lag luam thiab lwm yam kev lag luam tshuaj txhua hnub.

Kev ua tau zoo ntawm Chitosan Powder:

Chitosan yog ib hom cellulose nrog kev saib xyuas kev noj qab haus huv, uas muaj nyob rau hauv lub cev ntawm crustacean tsiaj los yog kab.

Chitosan muaj txiaj ntsig zoo rau kev tswj cov ntshav lipids, tshwj xeeb tshaj yog rau txo cov roj cholesterol. Nws tuaj yeem tiv thaiv kev nqus ntawm cov rog hauv cov zaub mov, thiab tuaj yeem ua kom cov metabolism ntawm cov roj (cholesterol) qub uas twb muaj lawm hauv tib neeg cov ntshav.

Chitosan tseem tuaj yeem cuam tshuam cov kab mob ua haujlwm, thiab tuaj yeem tiv thaiv thiab tswj ntshav siab.

Chitosan kuj muaj qhov zoo tshaj plaws, uas yog, nws muaj peev xwm adsorb, uas tuaj yeem pab adsorb thiab tso tawm cov hlau hnyav.

Piv txwv li, cov neeg mob hnyav hlau lom, tshwj xeeb tshaj yog tooj liab lom, tuaj yeem adsorbed nrog chitosan.

Chitosan tseem tuaj yeem nqus cov protein, txhawb kev kho qhov txhab, thiab pab cov ntshav coagulation nrog hemostasis.

Nyob rau tib lub sijhawm, nws tuaj yeem muaj kev ua haujlwm immunomodulatory thiab tiv thaiv kev mob.
