Substrate conversions of yeast <i>Saccharomyces cerevisiae</i> transformed with pYES2 containing the open reading frame (ORF) of the <i>Paracentrotus lividus</i> desaturases (FadsC1, FadsA and FadsC2).

Results are expressed as a percentage of total fatty acid (FA) substrate converted to desaturated products, with the corresponding activity (Δx) detected also shown. FA are designated using the ‘n-‘ nomenclature, except for the non-methylene interrupted FA produced from 20:3n-3 and 20:2n-6 where the ‘Δ’ nomenclature is used.
