Mafuta ofunikira a n-3 α-linolenic acid (C18: 3) amagwira ntchito ngati chonyamulira mphamvu ndi kalambulabwalo wa kaphatikizidwe ka EPA (C20: 5) ndi DHA (C22: 6) momwe amasinthidwa ndi kufalikira kwa unyolo ndi kuyambika. za ma bond owonjezera awiri.EPA ndi gawo lofunikira la phospholipids ya cell membranes ndi lipoproteins.Imagwiranso ntchito ngati kalambulabwalo wa kaphatikizidwe ka eicosanoids, yomwe imakhala ndi ntchito yowongolera mahomoni a minofu.DHA ndi gawo lamapangidwe am'maselo a cell, makamaka minofu yamanjenje yaubongo, ndipo imagwira ntchito yofunika kwambiri pama synapses ndi ma cell a retina.
Kutembenuka kwa α-linolenic acid ku zotengera zake zazitali EPA ndi DHA sikungakhale kokwanira kuti thupi lizigwira ntchito bwino.Kutembenuka kochepa kumatheka makamaka chifukwa cha kusintha kwakukulu kwa zakudya m'zaka zapitazi za 150, zomwe zimapangitsa kuti n-6 PUFA idye kwambiri komanso kuchepetsa kudya kwa n-3 LCPUFA m'mayiko ambiri olemera.Chifukwa chake, chiŵerengero cha n-6 mpaka n-3 muzakudya zathu chasintha kuchokera ku 2: 1 mpaka pafupifupi 10 - 20: 1.Kusintha kumeneku kumapangitsa kuti biosynthesis yosakwanira ya biologically active n-3 PUFA, EPA, ndi DHA, monga n-6 ndi n-3 PUFA amapikisana ndi machitidwe a enzyme desaturase ndi elongase.
