Lipase Catalyzed Incorporation of Conjugated Linoleic Acid by Transesterification into Sunflower Oil Applying Immobilized Lipase (Lipozyme Thermomyces lanuginosus and Rhizomucor mehei)
Conjugated Linoleic Acid (CLA), Glycerol (G) and sunflower oil blends with varying concentration were subjected to enzymatic esterification using a 1, 3- specific immobilized lipase. CLA was used as acyl due to its purported health benefits. The transesterified lipids were evaluated for free fatty acids (FFA) and composition of fatty acids by gas chromatography. Lipozyme RM IM is preferred for ...
متن کاملTransesterification of trimethylphosphate catalyzed by sodium aloxides
The transesterification process of trimethylphosphate with ethanol and isopropanol is examined. It is found that the reaction does not proceed in the absence of base even at temperature up to 100°C, whereas in the presence of sodium alkoxide as a catalyst it takes place at room temperature leading to a mixture of mono-,bi-, tri-substitute esters as well as the minor by-products resulting from t...
متن کاملSynthesis of structured triacylglycerols enriched in n-3 fatty acids by immobilized microbial lipase
The search for new biocatalysts has aroused great interest due to the variety of micro-organisms and their role as enzyme producers. Native lipases from Aspergillus niger and Rhizopus javanicus were used to enrich the n-3 long-chain polyunsaturated fatty acids content in the triacylglycerols of soybean oil by acidolysis with free fatty acids from sardine oil in solvent-free media. For the immob...
متن کاملLipase-Catalyzed Transesterification of Egg-Yolk Phophatidylcholine with Concentrate of n-3 Polyunsaturated Fatty Acids from Cod Liver Oil.
Phospholipids containing PUFAs are important vehicles for their delivering to the targeted tissues. In our research project we established enzymatic methods for the enrichment of natural egg-yolk PC with n-3 PUFAs. Instead of synthetic PUFA ethyl esters, the new strategy was developed using polyunsaturated fatty acids enriched fraction (PUFA-EF) from cod liver oil as the natural acyl donors. PU...
متن کاملTransesterification reactions catalyzed by chymotrypsin.
As recently reported, the behavior of acetyl chymotrypsin with ethanol consists in a rapid transfer of the single acetyl group to that alcohol with the formation of ethyl acetate (1). Thus, the splitting of nitrophenyl acetates by chymotrypsin, faster in ethanolic than in aqueous solutions, may be explained by the formation of acetyl chymotrypsin as an intermediate and its subsequent preferenti...
