Qhov thib ob, thaum cov pej xeem thoob ntiaj teb muaj hnub nyoog thiab qhov tshwm sim ntawm kev poob qis ntawm lub hlwb uas cuam tshuam nrog hnub nyoog nce ntxiv, kev piav qhia txog lub luag haujlwm ntawm phospholipids hauv kev laus ntawm lub hlwb yuav tseem ceeb dua rau kev txhawb nqa kev laus noj qab haus huv thiab khaws cia kev ua haujlwm ntawm lub hlwb. Qhov thib peb, qhov kev hloov pauv ntawm cov khoom phospholipid los ntawm kev noj zaub mov thiab kev cuam tshuam ntawm kev ua neej qhia txog qhov tseem ceeb ntawm kev paub thiab kev kawm txog cov peev txheej thiab cov txiaj ntsig ntawm phospholipids hauv kev txhawb nqa kev ua haujlwm ntawm lub hlwb. Ntxiv mus, kev nkag siab txog qhov cuam tshuam ntawm phospholipids rau kev noj qab haus huv ntawm lub hlwb yog qhov tseem ceeb rau kev qhia cov tswv yim kev noj qab haus huv pej xeem, kev cuam tshuam hauv kev kho mob, thiab cov txheej txheem tus kheej uas tsom mus rau kev txhawb nqa kev ua siab ntev ntawm lub hlwb thiab txo qhov kev poob qis ntawm lub hlwb.
Xaus lus, qhov cuam tshuam ntawm phospholipids rau kev noj qab haus huv ntawm lub hlwb thiab kev ua haujlwm ntawm lub hlwb yog ib qho kev tshawb fawb ntau yam thiab muaj zog nrog rau qhov cuam tshuam loj rau kev noj qab haus huv pej xeem, kev kho mob, thiab kev noj qab haus huv ntawm tus kheej. Raws li peb txoj kev nkag siab txog lub luag haujlwm ntawm phospholipids hauv kev ua haujlwm ntawm lub hlwb txuas ntxiv mus, nws yog ib qho tseem ceeb kom paub txog lub peev xwm ntawm kev cuam tshuam thiab cov tswv yim tus kheej uas siv cov txiaj ntsig ntawm phospholipids rau kev txhawb nqa kev ua kom lub hlwb muaj zog thoob plaws lub neej. Los ntawm kev koom ua ke cov kev paub no rau hauv kev pib kho mob pej xeem, kev kho mob, thiab kev kawm, peb tuaj yeem txhawb kom cov tib neeg ua cov kev xaiv uas txhawb nqa kev noj qab haus huv ntawm lub hlwb thiab kev ua haujlwm ntawm lub hlwb. Thaum kawg, kev txhawb nqa kev nkag siab txog qhov cuam tshuam ntawm phospholipids rau kev noj qab haus huv ntawm lub hlwb thiab kev ua haujlwm ntawm lub hlwb muaj kev cog lus rau kev txhim kho cov txiaj ntsig ntawm lub hlwb thiab txhawb kev laus noj qab haus huv.
