α-Cyclodextrin CAS 10016-20-3
α-Cyclodextrin (feem ntau hu ua CD) yog ib lo lus dav dav rau ib chav kawm ntawm cov cyclic compounds uas muaj D-pyranose glucose units txuas nrog kawg mus rau qhov kawg los ntawm alpha-1,4-glycosidic bonds, uas yog tsim los ntawm starch lossis polysaccharides nyob rau hauv qhov kev ua ntawm cyclodextrin glucosyltransferase. Cov molecules feem ntau muaj 6, 7 thiab 8 glucose units, uas hu ua α-cyclodextrin, β-cyclodextrin thiab γ-cyclodextrin hauv Chemicalbook. Txij li thaum α-cyclodextrin tuaj yeem tsim cov complexes nrog ntau tus qhua molecules, yog li hloov cov khoom siv lub cev thiab tshuaj ntawm cov qhua molecules xws li solubility thiab stability, nws muaj ntau yam kev siv hauv zaub mov, tshuaj, kev ua liaj ua teb, textiles, kev tiv thaiv ib puag ncig, tshuaj pleev ib ce, biotechnology thiab analytical chemistry.

1. Kev lag luam tshuaj: Cyclodextrin siv tau los tsim cov tshuaj sib xyaw ua ke (encapsulation), uas tuaj yeem ua kom cov tshuaj tsis ruaj khov; hloov cov khoom deliquescent, nplaum lossis kua ua hmoov; hloov cov khoom tsis yaj lossis tsis yaj ua cov khoom yaj (solubilization), thiab lwm yam.
2. Kev lag luam tshuaj tua kab: Kev ruaj khov ntawm cyclodextrin tuaj yeem ua rau qee cov tshuaj tua kab tiv taus kev khaws cia thiab txhim kho kev ua haujlwm ntawm cov tshuaj tua kab.
3. Kev lag luam zaub mov: Cyclodextrin siv rau hauv kev lag luam zaub mov kom muaj cov teebmeem hauv qab no: tshem tawm thiab npog cov ntxhiab tsw tshwj xeeb; txhim kho thiab txhim kho cov qauv zaub mov; txo thiab tshem tawm cov saj iab; cov nyhuv antioxidant; khaws cia thiab ua kom zoo dua ntawm cov saj.
4. Kev lag luam tshuaj lom neeg txhua hnub: Cyclodextrin kuj tseem siv tau ua cov emulsifier thiab cov khoom zoo hauv kev tsim cov tshuaj pleev ib ce. Nws kuj muaj cov teebmeem deodorizing (xws li tshem tawm cov pa phem) thiab cov teebmeem preservative, thiab tuaj yeem siv rau hauv kev tsim cov tshuaj txhuam hniav thiab hmoov hniav.
5. Tshuaj pleev ib ce: Cyclodextrin kuj tseem siv tau ua cov emulsifier thiab cov khoom zoo dua hauv kev tsim cov tshuaj pleev ib ce. Nws kuj muaj cov teebmeem deodorizing (xws li tshem tawm cov pa phem) thiab cov teebmeem preservative, thiab tuaj yeem siv rau hauv kev tsim cov tshuaj txhuam hniav thiab hmoov hniav.
6. Cov khoom noj khoom haus ntxiv: Cov khoom ua kom tuab siv dav hauv cov khoom noj (xws li cov khoom noj khoom haus ntxiv uas ua rau cov khoom noj khoom haus viscosity ntau ntxiv lossis tsim cov gels hauv cov kua ntses, jams, ice cream, zaub mov hauv kaus poom, thiab lwm yam), tshuaj pleev ib ce, tshuaj ntxuav tes, roj hmab, luam ntawv thiab zas xim, tshuaj, roj hmab, txheej, thiab lwm yam.
7. Cov Tsw Qab thiab Cov Tshuaj Tsw Qab: Cyclodextrin kuj siv dav hauv kev ua cov tsw qab thiab cov tshuaj tsw qab. Nws tuaj yeem siv los qhwv thiab tso cov tshuaj tsw qab, yog li txhim kho kev ruaj khov thiab tso tawm cov tshuaj tsw qab thiab cov tshuaj tsw qab.
8. Kev lag luam pub tsiaj: Hauv kev lag luam pub tsiaj, α-cyclodextrin tuaj yeem siv los ua cov khoom ntxiv los txhim kho cov khoom siv lub cev ntawm cov tsiaj pub tsiaj, ua kom cov khoom noj muaj txiaj ntsig zoo ntawm cov tsiaj pub tsiaj, thiab pab zom zaub mov thiab nqus tau.
