Cov roj (cholesterol) tseem yog qhov tseem ceeb ntawm kev txiav txim siab ntawm daim nyias nyias ntawm cov kua dej membrane fluidity Nyob rau hauv biology, membrane fluidity yog hais txog cov viscosity ntawm lipid bilayer ntawm lub cell membrane los yog hluavtaws lipid membrane … ob daim ntawv cog lus nce fluidity. Membrane fluidity kuj cuam tshuam los ntawm cov roj cholesterol. Cov roj (cholesterol) tuaj yeem ua rau cov cell membrane ua kua thiab ua kom nruj. https://en.wikipedia.org › wiki › Membrane_fluidity

Membrane fluidity - Wikipedia

: ntawm qhov kub thiab txias, cov roj cholesterol ua kom ruaj khov ntawm cov cell membrane thiab nce nws cov ntsiab lus melting; Thaum qhov kub tsis txias, nws nkag mus rau hauv phospholipids thiab tiv thaiv lawv los ntawm kev cuam tshuam rau ib leeg kom tsis txhob sib sau ua ke [39].

Puas cov roj cholesterol stabilize daim nyias nyias?

Cholesterol stabilizes lub qauv ntawm M2 proton channel hauv lub hnab ntawv ua npaws.

Puas cov roj cholesterol txhawb lub cell membrane?

Cov roj (cholesterol) yog qhov tseem ceeb rau kev tsim cov cell membrane thiab cov qauv ntawm testhiab tseem ceeb heev rau kev sib txuas ntawm cov tshuaj hormones, vitamin D thiab lwm yam tshuaj.
