A lipid monolayer yog tsim los ntawm kev sib kis ntawm cov lipids yaj hauv cov kuab tshuaj tsis muaj zogxws li pentane ntawm cov dej.
lipid monolayer yog dab tsi?
Lipid monolayers yog siv los ua cov qauv kev sim los kawm txog lub cev tshuaj lom neeg ntawm biomembranes. Nrog rau lub hom phiaj no, qhov chaw siab / cheeb tsam ib qho molecule isotherms muab ib txoj hauv kev kom tau txais cov ntaub ntawv ntawm kev ntim khoom thiab compressibility zog ntawm lipids.
Dab tsi yog ib daim nyias nyias?
Langmuir monolayers feem ntau yog siv los ua cov cell membrane los kawm txog cov teebmeem ntawm cov tshuaj lossis cov co toxins. Hauv kab lis kev cai cell monolayer yog hais txog ib txheej ntawm cov hlwb uas tsis muaj cell loj hlob nyob rau sab saum toj ntawm lwm tus, tab sis txhua tus loj hlob ib sab thiab feem ntau kov ib leeg rau tib qho kev loj hlob.
Dab tsi yog nyob rau hauv lipid bilayer?
Feem ntau cov bilayers ntuj yog tsim los ntawm phospholipids, tab sis sphingolipids thiab sterols xws li cov roj cholesterol kuj yog cov khoom tseem ceeb. Ntawm cov phospholipids, feem ntau headgroup yog phosphatidylcholine (PC), accounting txog li ib nrab ntawm phospholipids nyob rau hauv feem ntau cov tsiaj cov hlwb.
Kev ua haujlwm ntawm lipid monolayer hauv lipoproteins yog dab tsi?
Plasma lipoprotein particles
Lub luag haujlwm ntawm lipoprotein hais yog thauj cov roj molecules, xws li triacylglycerols (tseem hu ua triglycerides), phospholipids, thiab cov roj cholesterol hauv covdej extracellular ntawm lub cev mus rau tag nrho cov hlwb thiab cov ntaub so ntswg ntawm lub cev.
