Thaum lub lipid bilayer muab cov qauv rau lub cell membrane , membrane proteins tso cai rau ntau qhov kev sib tshuam uas tshwm sim ntawm hlwb . Raws li peb tau tham hauv tshooj dhau los, membrane proteins yog dawb rau txav nyob rau hauv lub lipid bilayer vim nws fluidity.

Yog li, yuav ua li cas cov protein txav hauv daim nyias nyias?

Kev thauj mus los proteins txav molecules thiab ions nyob rau hauv daim nyias nyias . Lawv ua tau yuav categorized raws li rau Transporter Classification database. Membrane enzymes yuav muaj ntau yam dej num, xws li oxidoreductase, transferase lossis hydrolase. Cell adhesion molecules tso cai rau cov cell rau txheeb xyuas ib leeg thiab sib tham.

Tsis tas li ntawd, nyob qhov twg cov proteins pom nyob rau hauv lub cell membrane? Peripheral membrane proteins yog pom nyob rau sab nraud thiab sab hauv ntawm daim nyias nyias , txuas nrog rau ib qho cov proteins los yog phospholipids. Tsis zoo li ib qho membrane proteins , peripheral membrane proteins tsis txhob lo rau hauv cov tub ntxhais hydrophobic ntawm lub daim nyias nyias , thiab lawv zoo li yuav ua tau yooj yim dua.

Ib yam li ntawd, nws tau nug, dab tsi yog 3 cov proteins hauv cell membrane?

Raws li lawv cov qauv, muaj lub ntsiab peb hom ntawm membrane proteins : thawj tus yog integral daim nyias nyias protein uas yog nyob mus ib txhis anchored los yog ib feem ntawm lub daim nyias nyias , hom thib ob yog peripheral daim nyias nyias protein uas tsuas yog txuas rau ib ntus rau lipid bilayer lossis rau lwm qhov sib xyaw cov proteins , thiab peb

Dab tsi yog cov haujlwm ntawm cov protein hauv cov cell membrane?

Membrane proteins tuaj yeem ua haujlwm ua enzymes kom ceev cov tshuaj tiv thaiv, ua raws li cov receptors rau cov molecules tshwj xeeb, lossis thauj cov ntaub ntawv hla lub cell membrane. Carbohydrates, los yog suab thaj, qee zaum pom txuas nrog cov proteins lossis lipids sab nraud ntawm lub cell membrane.
