(9Z,11E,13S)-13-hydroperoxy-9,11-octadecadienoate an essentially complete loss of isotope is noted with the (14R)-deuterated precursor, whereas incubation of the (14S)-deuterated precursor affords products that retain most of the deuterium label Allium sativum (9Z,11E)-12-[(1E)-hex-1-en-1-yloxy]dodeca-9,11-dienoic acid + H2O i.e. etheroleic acid ?

additional information irrespective of which hydroperoxide regioisomer serves as the substrate, divinyl ether synthases abstracting the pro-R hydrogen generate divinyl ethers having an E vinyl ether double bond, whereas enzymes abstracting the pro-S hydrogen produce divinyl ethers having a Z vinyl ether double bond Allium sativum ?
