Hauv kev xaus, qhov cuam tshuam ntawm phospholipids ntawm lub hlwb kev noj qab haus huv thiab kev paub txog kev ua haujlwm yog ntau qhov chaw thiab muaj zog ntawm kev tshawb fawb nrog kev cuam tshuam tseem ceeb rau pej xeem kev noj qab haus huv, kev kho mob, thiab kev noj qab haus huv ntawm tib neeg. Raws li peb txoj kev nkag siab txog lub luag haujlwm ntawm phospholipids hauv kev paub txog kev ua haujlwm txuas ntxiv mus, nws yog qhov tseem ceeb kom paub txog lub peev xwm ntawm cov phiaj xwm kev cuam tshuam thiab cov tswv yim ntawm tus kheej uas siv cov txiaj ntsig ntawm phospholipids rau kev txhawb nqa kev txawj ntse thoob plaws lub neej. Los ntawm kev sib koom ua ke cov kev paub no rau hauv cov phiaj xwm kev noj qab haus huv rau pej xeem, kev coj noj coj ua, thiab kev kawm, peb tuaj yeem txhawb cov tib neeg kom paub cov kev xaiv uas txhawb nqa lub hlwb kev noj qab haus huv thiab kev txawj ntse. Thaum kawg, txhawb nqa kev nkag siab zoo ntawm qhov cuam tshuam ntawm phospholipids ntawm lub hlwb kev noj qab haus huv thiab kev paub txog kev ua haujlwm tau cog lus rau kev txhim kho kev txawj ntse thiab txhawb kev laus noj qab haus huv.
