Chitosan Cas 9012-76-4
Chitosan yog qhov thib ob biopolymer muaj ntau tshaj plaws hauv xwm tom qab cellulose, thiab nws tau faib dav dav, feem ntau yog faib rau hauv cov plhaub ntawm ntau cov tsiaj qis dua, tshwj xeeb tshaj yog arthropods xws li cw, crabs, kab, thiab lwm yam, thiab kuj muaj nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag qis dua xws li cov kab mob, algae thiab fungi. Chitosan yog tib qho amino polysaccharide yooj yim uas muaj nyob rau hauv ntau ntawm cov polysaccharides ntuj, nrog rau ntau yam khoom siv tshwj xeeb, thiab muaj ntau yam tseem ceeb ntawm kev siv hauv kev ua liaj ua teb thiab zaub mov, thiab lwm yam. Nws cov peev txheej nplua nuj, kev npaj yooj yim thiab kev tsim zaj duab xis, kev ua tau zoo heev, yuav ua lub luag haujlwm tseem ceeb hauv kev khaws cia cov tshuaj lom neeg hauv zaub mov, txuas ntxiv lub neej txee thiab lwm yam. Chitosan kuj muaj cov haujlwm ntawm kev txhim kho tib neeg lub cev tiv thaiv kab mob, tshem tawm cov rog ntau dhau hauv lub cev, tiv thaiv cov kab mob phem, txo cov ntshav lipids, tswj cov ntshav qab zib, tsis muaj tshuaj lom anticancer thiab siv ua biomedical khub.

Hauv kev ua liaj ua teb, chitosan ua rau cov lus teb tiv thaiv tus tswv tsev hauv monocotyledons thiab dicotyledons. Nws tau piav qhia tias yog tus neeg sawv cev tiv thaiv kab mob ntawm cov nroj tsuag thiab ua ib qho khoom ntxiv rau hauv cov kua ntau yam chiv. Tsis tas li ntawd, qhov muaj chitosan nyob rau hauv av ua rau muaj kev sib cuam tshuam ntawm cov nroj tsuag thiab cov kab mob me me. Chitosan kuj tseem tuaj yeem txhim kho cov metabolism ntawm cov nroj tsuag, ua rau muaj kev nce ntxiv ntawm cov noob germination thiab cov qoob loo.
Vim nws cov dej num tiv thaiv kab mob, cov khoom tiv thaiv kev coagulation, cov tshuaj tua kab mob thiab cov tshuaj tua kab mob fungal thiab nws lub luag haujlwm ua tus txhawb nqa kev kho qhov txhab hauv kev phais, chitosan tuaj yeem siv dav dav ua cov khoom siv biomedical. Tsis tas li ntawd, chitosan kuj tseem tuaj yeem siv ua cov khoom siv hauv daim ntawv ntawm cov granules lossis hlaws dai rau kev tso tawm cov tshuaj noj. Qhov no yog vim nws muaj ntau, cov khoom siv pharmacological thiab tsis muaj tshuaj lom.
Chitosan yog biocompatible thiab sib xws nrog lwm cov khoom xyaw xws li glucose, roj, rog thiab acids. Nws yog ib qho tshuaj hydrating zoo heev nrog lub peev xwm tsim zaj duab xis. Chitosan feem ntau siv rau hauv kev siv rau kev saib xyuas tawv nqaij. Nws pab khaws cov dej noo ntawm daim tawv nqaij, ua kom daim tawv nqaij noo thiab khov kho, muab kev txhawb nqa extracellular matrix thiab txhawb nqa daim tawv nqaij lub luag haujlwm ntuj.
Chitosan siv tau ua tus neeg sawv cev zoo heev thiab flocculant hauv kev kho dej khib nyiab, rov qab cov protein thiab ntxuav dej. Qhov no feem ntau yog vim muaj cov amino pawg ntau hauv cov saw polymer, uas tuaj yeem cuam tshuam nrog cov tshuaj tsis zoo xws li cov protein, cov khoom khov thiab cov xim.
Ntxiv rau cov ntawv thov hauv cov teb saum toj no, chitosan kuj tseem siv tau ua cov xim zas rau cov ntaub, cov khoom siv ntxiv rau hauv daim ntawv, thiab cov khoom siv tiv thaiv hauv cov khoom noj, thiab lwm yam.
25kg/nruas los ntawm hiav txwv los yog cua. Qhov cua hauv tsev rau khoom thiab qhov kub qis kom qhuav.
