Qhov tseem ceeb n-3 fatty acid α-linolenic acid (C18: 3) ua lub zog nqa thiab ua ntej rau kev sib txuas ntawm EPA (C20: 5) thiab DHA (C22: 6) rau hauv uas nws tau hloov los ntawm cov saw elongation thiab kev taw qhia. ntawm ob daim ntawv cog lus ntxiv.EPA yog ib qho tseem ceeb ntawm phospholipids ntawm cell membranes thiab lipoproteins.Nws kuj tseem ua haujlwm ua ntej hauv kev sib txuas ntawm eicosanoids, uas muaj kev tswj hwm kev ua haujlwm ntawm cov ntaub so ntswg cov tshuaj hormones.DHA yog ib qho kev tivthaiv nyob rau hauv lub cell membranes, tshwj xeeb tshaj yog cov paj hlwb ntawm lub paj hlwb, thiab plays ib tug tseem ceeb luag hauj lwm rau lub synapses thiab lub hlwb ntawm lub retina.
Kev hloov pauv ntawm α-linolenic acid rau nws cov khoom siv ntev ntev EPA thiab DHA yuav tsis txaus los tswj lub cev ua haujlwm zoo.Qhov kev hloov pauv tsawg feem ntau yog vim muaj kev hloov pauv loj ntawm kev noj zaub mov hauv 150 xyoo dhau los, uas ua rau nce n-6 PUFA kom tsawg thiab sib xyaw ua ke ntawm n-3 LCPUFA noj hauv ntau lub teb chaws industrialized.Yog li, qhov piv ntawm n-6 rau n-3 hauv peb cov zaub mov tau hloov ntawm 2: 1 txog 10 - 20: 1.Qhov kev hloov pauv no suav nrog qhov tsis txaus ntawm biosynthesis ntawm cov khoom siv roj ntsha n-3 PUFA, EPA, thiab DHA, raws li n-6 thiab n-3 PUFA sib tw rau tib lub desaturase thiab elongase enzyme systems.
