Qhov sib txawv tseem ceeb ntawm clathrates thiab cyclodextrin yog tias clathrates muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules, hos cyclodextrins yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits.
Clathrate compounds yog ib hom tshuaj lom neeg uas muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules. Cyclodextrin compounds yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits.
Clathrate yog dab tsi?
Clathrate tebchaw tuaj yeem piav qhia raws li hom tshuaj lom neeg uas muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules. Lo lus no muaj lub ntsiab lus Latin "nrog tuav, latticed." Feem ntau cov clathrate tebchaw zoo li yog cov tshuaj polymeric uas tuaj yeem ntim tag nrho cov qhua molecule. Txawm li cas los xij, hauv kev siv cov clathrates niaj hnub no, peb tuaj yeem soj ntsuam tus tswv tsev-tus qhua complexes thiab kev sib xyaw ua ke.
Daim duab 01: Cov Qauv Tshuaj ntawm Clathrate Xenon-Paraquinol
Raws li cov ntsiab lus muab los ntawm IUPAC, clathrate compounds yog ib hom kev sib xyaw ua ke uas muaj peev xwm tuav cov qhua molecule hauv ib lub tawb uas yog tsim los ntawm tus tswv molecule lossis los ntawm lattice ntawm tus tswv tsev molecules. Muaj ntau lub tswv yim molecular peb tuaj yeem siv lub npe no rau - piv txwv li, calixarenes thiab cyclodextrins. Tsis tas li ntawd, qee cov polymers inorganic xws li zeolites kuj yog clathrate compounds.
Peb tuaj yeem soj ntsuam tias feem ntau cov clathrate tebchaw yog muab los ntawm cov organic hydrogen daim ntawv cog lus, uas tau npaj los ntawm cov molecules uas tuaj yeem koom nrog tus kheej los ntawm ntau qhov sib cuam tshuam hydrogen-binding.
YCyclodextrin yog dab tsi?
Cyclodextrin compounds yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits. Cov subunits no tau koom ua ke los ntawm alpha 1, 4-glycosidic bonds. Cyclodextrin compounds feem ntau yog tsim los ntawm cov hmoov txhuv nplej siab los ntawm kev hloov enzymatic. Feem ntau, cov tshuaj no muaj txiaj ntsig zoo hauv zaub mov, tshuaj, xa tshuaj, tshuaj lom neeg kev lag luam, kev lag luam ua liaj ua teb, ib puag ncig engineering, thiab lwm yam.
Daim duab 02: Qee qhov piv txwv ntawm Cyclodextrin Compounds
Cyclodextrin compounds muaj tsib lossis ntau dua alpha-D-glucopyranoside units uas txuas los ntawm 1 txog 4, zoo ib yam li amylose. Feem ntau, muaj ntau cov piam thaj monomers uas muaj li ntawm rau txog rau yim units ib lub nplhaib. Qhov no tsim lub khob hliav qab.
Thaum xav txog kev siv cyclodextrins, cov no ua cov khoom xyaw hauv ntau cov tshuaj pom zoo xws li hydrocortisone, prostaglandin, nitroglycerin, itraconazol, thiab chloramphenicol. Ntxiv mus, beta-cyclodextrin yog ib qho tseem ceeb hauv chromatography los tsim ib theem nyob ruaj khov rau HPLC cov twj paj nruag. Tsis tas li ntawd, cyclodextrin muaj txiaj ntsig zoo hauv kev tsim cov hmoov cawv los ntawm kev ntim ethanol, thiab nws tuaj yeem khi cov tshuaj tsw qab.
Qhov txawv ntawm Clathrates thiab Cyclodextrin yog dab tsi?
Clathrates thiab cyclodextrins yog cov organic tebchaw tseem ceeb. Qhov sib txawv tseem ceeb ntawm clathrates thiab cyclodextrin yog tias clathrates muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules, hos cyclodextrins yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits.
Cov hauv qab no qhia txog qhov sib txawv ntawm clathrates thiab cyclodextrin hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Clathrates vs Cyclodextrin
Clathrate compounds yog ib hom tshuaj lom neeg uas muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules. Cyclodextrin compounds yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits. Yog li ntawd, qhov sib txawv tseem ceeb ntawm clathrates thiab cyclodextrin yog cov clathrates muaj cov lattice uas tuaj yeem ntxiab lossis muaj cov molecules, hos cyclodextrins yog ib tsev neeg ntawm cyclic oligosaccharides uas muaj lub nplhaib macrocyclic ntawm qabzib subunits.
