Cov hydrophilic taub hau interacts nrog cov polar molecules. Qhov no tso cai rau kev nkag mus ntawm cov protein, dej thiab ntau lwm cov molecules nkag mus rau hauv thiab tawm ntawm lub cell.

Hauv qhov no, vim li cas lub taub hau hydrophilic tseem ceeb?

Lub lipid bilayer yog teem rau hauv ob txheej ntawm phospholipids nrog rau hydrophilic taub hau tsim cov npoo sab nrauv thiab cov tails ua rau sab hauv. Qhov no yog tseem ceeb vim nws tso cai rau lub bilayer xaiv cov molecules uas nws yuav tso cai rau hauv thiab tawm ntawm tes.

Tsis tas li ntawd, hydrophobic tails ua dab tsi? Cov hydrophobic tails tiv thaiv polar molecules los yog ions kom dhau los ntawm daim nyias nyias. Cov kab hauv qab lawv yog ib qho thaiv tiv thaiv cov dej soluble. ib new hydrophobic Txoj kev tuaj yeem yog ib feem ntawm qhov loj ntawm cov plasma membrane ib qho.

Hauv qhov no, dab tsi ua rau lub taub hau ntawm phospholipid hydrophilic?

Ib leeg phospholipid molecule muaj ib pab pawg phosphate ntawm ib kawg, hu ua " taub hau ,” thiab ob sab-los-sab chains ntawm fatty acids uas ua nce lipid "tails.” Cov pab pawg phosphate raug nqi tsis zoo, ua rau taub hau polar thiab hydrophilic , los yog "kev hlub dej." Cov phosphate taub hau yog li attracted rau cov dej

Lub taub hau hydrophilic yog dab tsi?

Cov hydrophilic taub hau yog muaj li ntawm choline qauv (xiav) thiab phosphate (txiv kab ntxwv). Qhov no taub hau yog txuas nrog glycerol (ntsuab) nrog ob lub tails hydrophobic (ntsuab) hu ua fatty acids.
