Metabolic pathways and interconversions of PUFAs. Adapted from Gibson et al. (57) with permission from Elsevier. Not shown are the metabolic steps required for activation of FAs to enter the pathways, and the steps required to accept synthetic products from the pathway. Abbreviations: AdrA, adrenic acid; ALA, α-linolenic acid; ARA, arachidonic acid; β-oxy, β-oxydation; DGLA, di-homo-γ-linolenic acid; desat, desaturase; DPA³, docosapentaenoic acid n–3; DPA⁶, docosapentaenoic acid n–6; elong, elongase; GLA, γ-linolenic acid; LA, linoleic acid; SDA, stearidonic acid.
