context_page_description: Jasmonic acid is an organic compound found in several plants including jasmine. The molecule is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
context_section_description: Its biosynthesis starts from the fatty acid linolenic acid, which is oxygenated by Lipoxygenase (13-LOX), forming a peroxide. This peroxide then cyclizes in the presence of allene oxide synthase to form an allene oxide. This allene oxide rearranges as it gets catalyzed by the enzyme allene oxide cyclase to form 12-oxophytodienoic acid, and undergoes a series of β-oxidations to 7-iso-jasmonic acid. In the absence of enzyme, this iso-jasmonic acid isomerizes to jasmonic acid.
