Figure 1.
Simplified depiction of potential biosynthetic pathways of polyunsaturated fatty acids discussed in the current study (modified from Monroig and Kabeya 2018). Δx and ωx desaturases refer to the position of the added double bond; position of the added double bond is marked either from the methyl end (ω desaturases) or from the carboxyl end (Δ desaturases, also called front-end desaturases) of the acyl chain. Elongation reactions are marked with “Elo”.
