The catalytic activity of CYP175A1 toward monooxygenation of saturated and monounsaturated fatty acids of various chain lengths (C16-C24) has been investigated to assess the enzymatic properties of this orphan thermostable cytochrome P450 enzyme. The resu

Hydrogenation of methyl linoleate on palladium catalysts in solution with tetraalkylammonium perchlorate as electrolyte, leads mainly to the saturated product methyl stearate.At negative potentials of the catalyst electrode controlled at about -1 Volt versus a saturated calomel electrode (SCE) with negligible current passage, the monoenic intermediate is the end product, with the double bond found mainly in the Z configuration at the starting 9- and 12-positions.As expected it was found that methyl oleate was not hydrogenated by the catalyst held at -1.1 Volt, while smooth hydrogenation occurs under identical conditions when the catalyst potential is not controlled.Methyl linoleate leads mainly to dienoic esters at -1.8 V catalyst potential.The effect was applied on a synthetic scale in the hydrogenation of soya bean oil with palladium catalysts, resulting in a considerable increase of selectivity at negative catalyst potentials.
