dinor--12--oxo-Phytodienoic-Acid--d-5-

dinor-12-oxo Phytodienoic acid-d5 (dinor-OPDA-d5) contains five deuterium atoms at the 4, 4, 5, 5, and 5 positions. It is intended for use as an internal standard for the quantification of dinor-OPDA by GC- or LC-mass spectrometry (MS). In plants, certain unsaturated fatty acids are oxygenated and then further modified along the jasmonate pathway to produce plant hormones that are involved in senescence, flower development, mechanotransduction, and the response to herbivory. dinor-OPDA is an intermediate in the synthesis of jasmonic acid from hexadecatrienoic acid. dinor-OPDA can also be incorporated...
