15 صفحه اولHigh-level accumulation of oleyl oleate in plant seed oil by abundant supply of oleic acid substrates to efficient wax ester synthesis enzymes
Background Biotechnology enables the production of high-valued industrial feedstocks from plant seed oil. The plant-derived wax esters with long-chain monounsaturated acyl moieties, like oleyl oleate, have favorite properties for lubrication. For biosynthesis of wax esters using acyl-CoA substrates, expressions of a fatty acyl reductase (FAR) and a wax synthase (WS) in seeds are sufficient. R...
متن کاملContinuous Synthesis of Oleyl Oleate in Supercritical Carbon Dioxide using Solid p-Toluenesulfonic Acid as Catalyst
Supercritical carbon dioxide (SC-CO2) was used as solvent to synthesize oleyl oleate as an analog of Jojoba oil from oleic acid and oleyl alcohol with high conversion (100%) of the acid into ester in a short time of 100 min. Utilizing a low cost solid catalyst, p-toluenesulfonic acid monohydrate (PTSA), the esterification reaction was performed, without any prior preparation step...
متن کاملSynthesis of 8-Stearolactone from Oleic Acid
8-Stearolactone was prepared from oleic acid using concentrated sulfuric acid under various conditions in the presence of polar, nonparticipating solvents. 8-Stearolactone was formed in as high as 15:1 ratios over the thermodynamic product, y-Iactone, in the presence of methylene chloride, 100% wt/vol, at room temperature with two equivalents of sulfuric acid for 24 h. This procedure is applica...
متن کاملThe enzymatic synthesis of wax in liver.
Wax. The product was isolated by column chromatography and repeated thin layer chromatography. It was identified by thin layer chromatography, by analysis of the hydrolysis products, and by gas chromatography. Microsomal and supematant fractions of liver were active. Synthesis was stimulated by detergents such as Triton X-100, Tween 20, and bile salts. Wax formation occurred without activation,...
