Petroselinic acid (18:1Δ6) is the major component of the seed oil of Umbelliferae species such as coriander (Coriandrum sativum) as well as Araliaceae and Garryaceae species. This unusual fatty acid is synthesized in plastids by the Δ4 desaturation of palmitoyl-acyl carrier protein (16:0-ACP) and subsequent elongation of Δ4-hexadecenoyl (16:1Δ4)-ACP. To characterize the enzymatic nature of the elongation reaction, an in vitro assay was developed with 16:1Δ4-ACP and 16:0-ACP as substrates… CONTINUE READING
