Cov qauv ntawm phospholipid molecule muaj ob lub hydrophobic tails ntawm fatty acids thiab ib lub taub hau hydrophilic ntawm phosphate moiety, sib koom ua ke los ntawm cawv lossis glycerol molecule [90]. Vim tias qhov kev tsim qauv no, PLs tsim cov lipid bilayers thiab yog ib feem tseem ceeb ntawm tag nrho cov cell membranes.

Tus qauv thiab kev ua haujlwm ntawm phospholipid yog dab tsi?

Phospholipids muaj xws li hydrophilic (los yog 'dej hlub') taub hau thiab hydrophobic (los yog 'dej ntshai') tail. Phospholipids nyiam ua kab thiab npaj lawv tus kheej rau hauv ob txheej sib luag, hu ua phospholipid bilayer. Cov txheej no ua rau koj cov cell membranes thiab tseem ceeb heev rau lub cell lub peev xwm ua haujlwm.

Qhov twg zoo tshaj piav qhia txog cov qauv ntawm phospholipid?

1: Ib qho phospholipid muaj lub taub hau thiab tus Tsov tus tw"lub taub hau" ntawm cov molecule muaj cov phosphate pawg thiab yog hydrophilic, txhais tau tias nws yuav yaj hauv dej. Lub "tail" ntawm lub molecule yog tsim los ntawm ob fatty acids, uas yog hydrophobic thiab tsis yaj nyob rau hauv dej.

Tus qauv ntawm phospholipids quizlet yog dab tsi?

Tus qauv ntawm phospholipids yog dab tsi? glycerol lossis sphingosine qaum nrog ob txoj hlua fatty acid thiab ib pawg polar taub hau uas muaj phosphate txuas rau glycerol thiab ib pawg R.

Cov khoom tseem ceeb ntawm phospholipid yog dab tsi?

Phospholipids muaj ntau nyob rau hauv tag nrho cov kab mob lom. Ib qho phospholipid molecule yog tsim los ntawm plaub yam: fatty acids, lub platform uas cov fatty acids txuas, phosphate, thiab ib qho cawv txuas rau phosphate(Daim duab 12.3).
