Micelles yog tsim by self-assembly ntawm amphiphilic molecules. Cov qauv muaj thaj tsam hydrophilic/polar (lub taub hau) thiab hydrophobic/nonpolar cheeb tsam (tail) [1]. Cov micelles yog tsim nyob rau hauv aqueous tov uas yog lub polar cheeb tsam fim sab nraud ntawm lub micelle thiab lub nonpolar cheeb tsam tsim lub core.
micelles tsim Chav Kawm 10 li cas?
Lub ionic-kawg ntawm xab npum dissolves nyob rau hauv dej thaum lub carbon saw dissolves nyob rau hauv roj. Cov xab npum molecules, yog li tsim cov qauv hu ua micelles. … Qhov no yog ua tiav los ntawm kev tsim pawg ntawm cov molecules uas cov tails hydrophobic nyob rau sab hauv ntawm pawg thiab cov ionic kawg yog nyob rau saum npoo ntawm pawg.
micelle tsim hauv chemistry yog dab tsi?
Micelle, hauv lub cev chemistry, kev sib sau ua ke ntawm ntau kaum lossis ntau pua lub atoms, ions (hluav taws xob atoms), lossis molecules, ua ib qho colloidal particle-ie, ib qho ntawm ib tug xov tooj ntawm ultramicroscopic particles dispersed los ntawm ib co nruam nruab nrab.
Qhov laj thawj tseem ceeb ntawm kev tsim micelle yog dab tsi?
Micelles yog tsim los ntawm qhov tseem ceeb micelle concentration (CMC), uas tau kuaj pom tias yog qhov kis tau tus mob thaum lub cev muaj zog xws li qhov nro saum npoo yog plotted raws li kev ua haujlwm ntawm concentration (Daim duab 4.7). Qhov laj thawj tseem ceeb ntawm kev tsim micelle yog qhov ua tiav ntawm lub xeev yam tsawg kawg nkaus pub dawb.
micelles pom nyob qhov twg?
Bile ntsev formed in thedaim siab thiab zais los ntawm lub zais zis tso cai rau micelles ntawm fatty acids tsim. Qhov no tso cai rau kev nqus ntawm cov lipids nyuaj (xws li lecithin) thiab lipid-soluble vitamins (A, D, E, thiab K) hauv micelle los ntawm txoj hnyuv me.
