Fig. 6From: Comparative analysis reveals unexpected genome features of newly isolated Thraustochytrids strains: on ecological function and PUFAs biosynthesisThe predicted FAS pathway for the DHA biosynthesis in KEGG. The stearic acid (C16:0) is successively desaturated and elongated through a series of reactions leading to the formation of n-3 and n-6 PUFAs. There exist n-3 desaturases that can convert n-6 PUFAs into DHABack to article page
