(9S,10E,12Z)-9-hydroperoxy-10,12-octadecadienoate selective removal of the pro-R hydrogen at C-8 in the biosynthesis of colneleic acid. Generation of colneleic acid from the (8R)-deuterated (9S)-hydroperoxide is accompanied by loss of most of the deuterium label (retention, 8%) Solanum tuberosum (8E)-9-[(1E,3Z)-nona-1,3-dien-1-yloxy]non-8-enoic acid + H2O i.e. colneleate ?
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 Solanum tuberosum ?
