Substance production

Codlemone is produced commercially through a process called metabolic engineering. This involves genetically modifying a crop (often Camelina sativa) to produce codlemone precursors. The crop is then cultivated, harvested and seeds collecting containing the codlemone precursors. The fatty acids in the seeds are extracted and converted into the corresponding alcohols, which are the active components of codlemone.
