Biosynthetic pathway of n3 and n6 PUFAs highlighting a set of genes known to play key roles in the biosynthesis and metabolism of LC-PUFAs in two parallel and competing pathways. Enzymatic products from these genes convert 18-carbon (18C) n-6 or n-3 essential PUFAs (abundant in the modern western diet [MWD]) into LC-PUFA.
