The current work was to evaluate the lipase-catalyzed acidolysis of corn oil with caprylic acid (CA) in organic system under bath ultrasonic pretreatment and to analyze the physicochemical properties of structured lipids (SLs). Under optimum conditions (Novozym 40086 lipase, 200 W ultrasound power,
The effects of fish oil and corn oil on plasma lipoprotein concentrations, the lipolytic enzymes, lipoprotein lipase and hepatic triacylglycerol lipase, the density distribution of the plasma lipoproteins and LDL receptor activity were studied. These experiments were designed, in part, to define the
The hydrolysis of corn oil in the presence of a lipase from Pseudomonas sp. immobilized within the walls of a hollow-fiber reactor was studied at 30 degrees C. To assess the selectivity of this immobilized enzyme, the effluent concentrations of five different free fatty acids were measured using
The kinetics of the hydrolysis of corn oil in the presence of a lipase from Pseudomonas sp. immobilized within the walls of a hollow fiber reactor can be modeled in terms of a three-parameter rate expression. This rate expression consists of the product of a two-parameter rate expression for the
The objective of this study was to investigate the influence of globular protein interfacial cross-linking on the in vitro digestibility of emulsified lipids by pancreatic lipase. 3% (wt/wt) corn oil-in-water emulsions stabilized by either lecithin or beta-lactoglobulin were prepared (pH 7). A
Our objective was to investigate the time course of postprandial lipemia and lipolytic activity in male Sprague-Dawley rats trained to eat meals containing butterfat fractions, palm oil or corn oil. Baseline and postprandial blood samples were obtained via a carotid cannula in rats fed the
The present study was undertaken to compare plasma lipoprotein lipid composition, as well as white adipose tissue lipoprotein lipase activity, in rats fed purified diets high in either sucrose or corn oil. The experimental diets (65% of calories as sucrose or corn oil, 15% as the opposite nutrient,
Biodiesel [fatty acid methyl esters (FAMEs)] and glycerol carbonate were synthesized from corn oil and dimethyl carbonate (DMC) via transesterification using lipase (Novozyme 435) in solvent-free reaction in which excess DMC was used as the substrate and reaction medium. Glycerol carbonate was also
The lipase from the scutella of corn (Zea mays) MO-17 seedlings was purified 272-fold to apparent homogeneity as evidenced by sodium dodecyl sulfate polyacrylamide gel electrophoresis and double immunodiffusion. The procedure involved isolation of the lipid bodies, extraction with diethyl ether,
In the process of screening for pancreatic lipase inhibitors, which could be used as an anti-obesity measure, the methanol extract of Dioscorea nipponica Makino powder (DP) appeared to have potent inhibitory activity against porcine pancreatic lipase with an IC50 value of 5-10 microg/ml, where the
OBJECTIVE
The present study was carried out to investigate effects of meals, rich in either saturated fatty acids (SFA), or n-6 or n-3 fatty acids, on postprandial plasma lipid and hormone concentrations as well as post-heparin plasma lipoprotein lipase (LPL) activity.
METHODS
The study was a
The consequences of hepatic lipase treatment of chylomicron remnants were studied. Rats were fed corn oil to induce production and secretion of chylomicrons and were then injected with polyclonal antiserum raised against hepatic lipase to specifically and quantitatively inhibit hepatic lipase
