Coconut Oil and Medium-Chain Triglycerides

All fats and oils are composed of fat molecules called fatty acids. There are two methods of classifying fatty acids. The one you are most familiar is based on saturation. You have saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids. The second method of classification is based on molecular size or length of the carbon chain in the fatty acid. You have short-chai...

Biodiesel Production via Esterification Reactions Catalyzed by Lipase

−− The synthesis of ethyl hexadecanoate was carried out by esterification of palmitic acid with ethanol in a solvent-free system. A commercial immobilized lipase (Lipozyme RM-IM) was mixed with the reagents, in a 15 mL closed batch reactor with constant stirring and coupled with a condenser. The effects of palmitic acid/ethanol molar ratio (0.16 to 1.84), reaction temperature (65 to 75C) and en...

Production of MLM-Type structured lipids from fish oil catalyzed by Thermomyces lanuginosus lipase

Background Lipases are powerful tools for the syntheses of structured lipids (SL) which are triacylglycerols (TAG) having particular fatty acid residues at specific positions. The production of TAG with medium chain fatty acids (MCFA), in positions sn-1 and sn-3, and a long-chain fatty acid (LCFA), in the internal position, has recently increased due to its nutritional interest in applications ...

Direct asymmetric aldol reactions catalyzed by lipase from porcine pancreas.

Porcine pancreas lipase type II (PPL II) exhibited unnatural catalytic activity in direct asymmetric aldol reactions between cyclic ketones and aromatic or heteroaromatic aldehydes in acetonitrile in the presence of phosphate buffer. A wide range of substrates was accepted by the enzyme to afford the corresponding aldol products in low to high yields (10-98%), with moderate to excellent enantio...

Two-step synthesis of fatty acid ethyl ester from soybean oil catalyzed by Yarrowia lipolytica lipase

BACKGROUND Enzymatic biodiesel production by transesterification in solvent media has been investigated intensively, but glycerol, as a by-product, could block the immobilized enzyme and excess n-hexane, as a solution aid, would reduce the productivity of the enzyme. Esterification, a solvent-free and no-glycerol-release system for biodiesel production, has been developed, and two-step catalysi...
