N-3 fatty acid α-linolenic acid (C18: 3) waxay u adeegtaa sida gudbiyaha tamarta iyo horudhaca isku dhafka EPA (C20: 5) iyo DHA (C22: 6) kaas oo loo beddelo silsilad dheereynta iyo hordhaca ee bonds dheeraad ah double.EPA waa qayb muhiim ah oo ka mid ah fosfoolipids ee xuubabka unugyada iyo lipoproteins.Waxa kale oo ay u adeegtaa sidii horudhac u ah isku-dhafka eicosanoids, kuwaas oo leh shaqo nidaamsan oo hormoonnada unugyada ah.DHA waa qayb ka mid ah qaab dhismeedka xuubka unugyada, gaar ahaan unugyada neerfayaasha ee maskaxda, waxayna door muhiim ah ka ciyaartaa synapses iyo unugyada retina.
Beddelka aashitada α-linolenic ee ka-soo-saarkeeda silsiladda dheer ee EPA iyo DHA waxaa laga yaabaa inaysan ku filnayn ilaalinta hawlaha jidhka ee ugu fiican.Beddelka xaddidan waxaa inta badan sabab u ah isbeddel weyn oo ku yimid caadooyinka cunnada intii lagu jiray 150kii sano ee la soo dhaafay, taasoo keentay kororka qaadashada n-6 PUFA iyo hoos u dhac wadajir ah ee isticmaalka n-3 LCPUFA ee inta badan waddamada warshadaha leh.Sidaa darteed, saamiga n-6 ilaa n-3 ee cuntadeena ayaa iska beddelay 2:1 ilaa 10 - 20:1.Isbeddelkan ayaa xisaabiya biosynthesis aan ku filnayn ee bayooloji firfircoon n-3 PUFA, EPA, iyo DHA, maaddaama n-6 iyo n-3 PUFA ay ku tartamayaan desaturase isku mid ah iyo nidaamyada enzym elongase.
