generation of (8Z)-colneleic acid from the (8R)-deuterated (9S)-hydroperoxide is accompanied by retention (98%) of most of the deuterium label
i.e. (8Z)-colneleic acid

irrespective of which hydroperoxide regioisomer served 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
