(±)-7-epi Jasmonic acid is the major metabolite of the 12-oxo phytodienoic acid pathway of the metabolism of 13(S)-hydroperoxy linolenic acid in plants. Initially synthesized as (+)-7-epi jasmonic acid, this more active and biologically relevant form of the hormone quickly epimerizes to the more stable isomer (−)-7-jasmonic acid. (±)-7-epi Jasmonic acid is a plant growth regulator that activates various signal transduction pathways with both growth promoting and inhibitory functions, perhaps in response to stress.

7-epi Jasmonic acid is the isomer of (±)-Jasmonic acid (HY-122464). (±)-Jasmonic acid is a plant growth regulator and a derivative of α-linolenic acid. (±)-Jasmonic acid decreases chlorophyll levels in green and etiolated barley leaf segments and inhibits elongation of rice seedlings.

ChEBI: (+)-7-isojasmonic acid is an oxylipin that is [(1S)-3-oxocyclopentyl]acetic acid substituted by a (2Z)-pent-2-en-1-yl group at position 2 on the cyclopentanone ring. It has a role as a member of jasmonates and a plant metabolite. It is an oxo carboxylic acid and an oxylipin. It is a conjugate acid of a (+)-7-isojasmonate.
