The enzymic formation of colneleic acid, a divinyl ether fatty acid: experiments with [(9S)-18O2]hydroperoxyoctadeca-(10E),(12Z)-dienoic acid
Abstract
Contrary to earlier reports, the oxygen inserted enzymically between carbons 9- and 10- of the C-18 chain in forming colneleic acid originates from 18O2 gas via the 9-hydroperoxide group of linoleic acid; a mechanism is proposed.
