Figure 1. n-6 and n-3 pathways of long chain polyunsaturated fatty acid (LC-PUFA) biosynthesis from essential fatty acids (EFAs).

Figure 1

Modified from [10,14,33]. LA, linoleic acid; GLA, γ- linolenic acid; DGLA, dihomo-γ-linolenic acid; AA, arachidonic acid; DTA, docosatetraenoic acid ALA, α-Linolenic acid; SA stearidonic acid; ETA eicosatetraenoic acid; EPA, eicosapentaenoic acid; DPA, docosapentaenoic acid; DHA, docosahexaenoic acid. D5D (Δ5-desaturase), D6D (Δ6-desaturase) and Elongase-5 enzymes are encoded by FADS1, FADS2 and ELOVL5, respectively.
