Docosahexaenoic acid (DHA) yog ib qho omega3 fatty acid uas yog lub luag haujlwm tseem ceeb hauv lub hlwb cortex, tawv nqaij, phev, testicles thiab retina.Nws tuaj yeem raug tsim los ntawm alphalinolenic acid lossis tau ncaj qha los ntawm niam mis lossis roj ntses.DHA tus qauv yog carboxylic acid (~ oic acid) nrog 22carbon saw thiab rau cis ob daim ntawv cog lus .thawj ob daim ntawv cog lus yog nyob rau ntawm peb cov pa roj carbon monoxide. omega kawg[3]Nws lub npe yog cervonic acid, nws lub npe yog tag nrho-cis-docosa-4,7,10,13,16,19-hexa-enoic acid, thiab nws lub npe luv yog 22: 6 (n-3) nyob rau hauv lub nomenclature ntawm fatty acids.
Qhov tseem ceeb n-3 fatty acid α linolenic acid (C18: 3) ua lub zog thauj khoom 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 ntxiv. ob daim ntawv cog lus.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 lub luag hauj lwm tseem ceeb 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 kom zoo.Qhov kev hloov pauv tsawg feem ntau yog vim muaj kev hloov pauv loj hauv kev noj zaub mov hauv 150 xyoo dhau los, ua rau nce n-6 PUFA kom tsawg thiab txo qis hauv n-3 LCPUFA.
noj nyob rau hauv feem ntau industrialized lub teb chaws.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 rau qhov tsis txaus ntawm biosynthesis ntawm cov khoom siv roj ntsha n-3 PUFA, EPA, thiab DHA, raws li n6 thiab n 3 PUFA sib tw rau tib lub desaturase thiab elongase enzyme systems.EPA-derived eicosanoids cuam tshuam cov txheej txheem tiv thaiv kab mob thiab ua tiav cov haujlwm tiv thaiv. .Tsis tas li ntawd, n-3 fatty acids muaj "noneicosanoid" ua haujlwm los ntawm lawv lub cev.Lawv muaj peev xwm hloov kho cov membrane fluidity, uas yog qhov tseem ceeb ntawm erythrocytes.
