11,12,13) Short chain EFA-Omega (6) (Linoleic Acid) and Omega 3 (Alpha linolenic acid) with the help of enzymes desaturase and elongase are converted to Long Chain Fatty Acids, AAArachidonic Acid, GLA-Gamma linolenic acid, DGLA-DihomoGLA, EPA-Eicosapentaenoic Acid, DHA- Docosahexaenoic Acid which are further converted to eicosanoids (PGProstaglandins, PGI-Prostacyclins, TX-Thromboxane by the enzyme Cyclooxygenase and LT-Leukotrienes by the enzyme15-Lypoxygenase).
