This forms 13-hydroperoxylinolenic acid, which is then modified by a dehydrase and undergoes cyclization by allene oxide cyclase to form 12-oxo-phytodienoic acid.
This biochemical process results in the creation of 13-hydroperoxylinolenic acid, which is then subjected to enzymatic modification by a dehydration reaction and eventually undergoes cyclization via an allene oxide enzyme to form 12-oxo-phytodienoic acid.
