Major biosynthetic pathways of polyunsaturated fatty acids (ω-3 and ω-6) with the interplay of desaturation (Δ5, Δ6) providing double bonds in cis geometric configuration (vertical arrows). The elongation step adds a two carbon atom-unit to the fatty acid chain (CE, chain elonagtion). * beta-oxidation.
