ChitosanthiabChitosan Oligosaccharideyog ob qho tib si polysaccharides muab tau los ntawm chitin, ib tug natural biopolymer pom nyob rau hauv lub exoskeletons ntawm crustaceans thiab cell phab ntsa ntawm fungi. Hauv qab no yog qee qhov zoo sib xws thiab qhov sib txawv ntawm chitosan thiab oligochitosan:
Zoo sib xws
1. Cov qauv tshuaj ntawm chitosan thiab oligochitosan zoo ib yam, ob qho tib si yog tsim los ntawm kev rov ua dua ntawm glucosamine thiab N-acetylglucosamine.
2. Ob leeg yog biodegradable, biocompatible thiab non-toxic, ua rau lawv zoo tagnrho rau ntau yam kev kho mob, tshuaj thiab ua liaj ua teb daim ntaub ntawv.
3. Ob leeg tau pom tias muaj txiaj ntsig zoo rau kev noj qab haus huv xws li tshuaj tua kab mob, tshuaj tua kab mob thiab tshuaj tiv thaiv kab mob.
4. Ob leeg tuaj yeem tsim los ntawm chitin los ntawm cov txheej txheem zoo sib xws xws li deacetylation thiab enzymatic hydrolysis.
Qhov txawv
1. Molecular hnyav
Qhov sib txawv tseem ceeb ntawm chitosan thiab chitooligosaccharide yog lawv qhov hnyav molecular. Chitosan muaj qhov hnyav molecular hnyav, feem ntau ntawm 50, 000 thiab ntau dua 1 lab Daltons, thaum oligosaccharides muaj qhov hnyav molecular, txij li ob peb puas mus rau ntau txhiab Daltons.
2. Solubility
Chitosan yog insoluble hauv dej, tab sis nws dissolves ntawm acidic pH vim nws cov amino pawg. Ntawm qhov tod tes, oligochitosan yog dej-soluble, ua rau nws yooj yim los lis thiab tawg.
3. Daim ntawv thov
Chitosan yog dav siv nyob rau hauv cov khoom noj, tshuaj pleev ib ce, tshuaj thiab lwm yam lag luam raws li bioactive khoom xyaw, stabilizers thiab tshuaj nqa. Ntawm qhov tod tes, vim nws qhov hnyav molecular qis thiab kev ua haujlwm lom neeg, oligochitosan tau nyiam ntau thiab ntau dua li cov khoom noj khoom haus zoo thiab ua haujlwm.
4. Kev ua si lom neeg
Kev ua haujlwm lom neeg ntawm chitosan thiab oligochitosan sib txawv nrog qhov hnyav molecular, qib ntawm deacetylation thiab saw ntev. Chitosan muaj zog tiv thaiv kab mob thiab tiv thaiv kab mob ntau dua li chitooligosaccharides, uas muaj zog antioxidant thiab immunomodulatory kev ua ub no.
Hauv cov ntsiab lus, chitosan thiab chitooligosaccharides muaj cov khoom zoo sib xws thiab kev siv, tab sis txawv ntawm qhov hnyav molecular, solubility, thiab lom lom.
