Khoom Taw Qhia
Vim tias sab nrauv yog hydrophilic thiab Cavity hydrophobic, cyclodextrin tuaj yeem muab qhov chaw hydrophobic binding site zoo li ib qho enzyme, ua tus tswv tsev uas muaj ntau yam tsim nyog qhua, xws li cov organic molecules, inorganic ions, thiab roj molecules. Cyclodextrins tau txais kev saib xyuas zoo thiab tau siv dav hauv kev lag luam catalysis, kev sib cais, zaub mov thiab tshuaj.
Ntxiv rau cov yam ntxwv thiab kev siv ntawm lwm cov CDS, vim hais tias lub puab kab noj hniav loj ntawm -CD yog me dua li ntawm -CD, nws yog tsim nyog rau kev suav nrog me me molecules, thiab daim ntaub ntawv yuav tsum tau siab CD solubility.
