The fat-soluble vitamins retinyl palm&ate, D,, E and K, were separated on a packed reversed-phase fused-silica capillary column using methanol-tetrahydrofran as mobile phase, and determined with UV detection. Conventional liquid chromatographic equipment was adapted for such purposes, providing a hi
Sllmmary: The synthesis of dehydroarachidonic acid derivatives l-3 is described together with their oxidation by soybean lipoxygenase. The results of these and kinetic studies suggest the occurrence of organoiron intermediates in lipoxygenation.
The interaction of furan fatty acids (F-acids) with lipoxygenase was investigated by incubation experiments of a synthetic dialkyl-substituted F-acid with soybean lipoxygenase-1. Originally the oxidation of furan fatty acids was assumed to be directly effected by lipoxygenase. It is now demonstrated
## Application of a polarity parameter model to the separation of fat-soluble vitamins by reversedphase HPLC The retention behavior of a series of fat-soluble vitamins has been established on the basis of a polarity retention model: log k = (log k) 0 + p (P m N -P s N ), with p being the polarity o
