Formation of unsaturated fatty acids: (left) biosynthetic pathways of MUFA starting from palmitic acid (SFA); (center) the omega-6 PUFA biosynthesis starting from linoleic acid; (right) the omega-3 PUFA biosynthesis starting from alpha-linolenic acid. Enzymes: ELO elongase; Δ5-, Δ6-, and Δ9-desaturase; β-oxidase. Numerical abbreviations describing the position and geometry of the double bonds (e.g., 9c), the notation of the carbon chain length and total number of double bonds (e.g., C18:2); in parenthesis, the used acronyms (e.g., ARA for arachidonic acid).
