Kwv yees li cas phospholipids npaj lawv tus kheej thaum lawv yog muab tso rau hauv a tsis muaj polar daws . Cov phospholipids yuav tsim ib tug bilayer. Cov phospholipid taub hau yuav orient rau lub daws . Cov phospholipid tails yuav orient rau lub daws.

Yog li ntawd, yuav ua li cas phospholipids feem ntau nonpolar npaj lawv tus kheej thaum lawv muab tso rau hauv dej?

Polar taub hau cheeb tsam nyob rau hauv pawg phosphate ntawm lub molecule yog hydrophilic (nrog rau dej ), thaum lub fatty acid tail yog hydrophobic (repelled los ntawm dej ). Thaum twg muab tso rau hauv dej , phospholipids yuav ua tau taw qhia lawv tus kheej nyob rau hauv ib tug bilayer nyob rau hauv uas tus tsis polar Tail cheeb tsam ntsib lub puab cheeb tsam ntawm lub bilayer.

Yuav ua li cas phospholipids npaj lawv tus kheej hauv dej? Hauv dej los yog aqueous tov, phospholipids nyiam npaj lawv tus kheej nrog lawv cov tails hydrophobic sib ntsib thiab lawv lub taub hau hydrophilic tig tawm.

Ib yam li ntawd, phospholipids npaj lawv tus kheej li cas hauv daim nyias nyias?

Phospholipids muaj ib tug hydrophilic (los yog 'dej hlub') taub hau thiab ib tug hydrophobic (los yog 'dej ntshai') tail. Phospholipids nyiam rau kab thiab npaj lawv tus kheej nyob rau hauv ob txheej parallel, hu ua a phospholipid bilayer. Cov txheej no ua rau koj lub cell daim nyias nyias thiab tseem ceeb heev rau lub peev xwm ntawm tes rau muaj nuj nqi

Yuav ua li cas phospholipids cuam tshuam nrog ib leeg?

Yog li, thaum ob peb phospholipids los yog glycolipids tuaj ua ke nyob rau hauv ib tug aqueous tov, hydrophobic tails sib tham sib los tsim ib lub chaw hydrophobic, thaum lub taub hau hydrophilic sib tham sib los ntawm kev tsim hydrophilic txheej rau txhua tus sab ntawm lub bilayer taw tes radically mus rau lub polar hnyav.
