Conversion of linoleic acid hydroperoxide by soybean lipoxygenase in the presence of guaiacol: identification of the reaction products.

abstract：:[3-(14)C] Eicosatrienoic acid (delta11,14,17) chemically synthesized from [-(14)C] linolenic acid was injected intracranially into 14-day old rats and sacrificed 8 hr later.
