Female Sprague-Dawley rats, 50 days of age, were treated with a single dose of 5 mg of 7,12-dimethylbenz(a)anthracene intragastrically. 3 days after carcinogen treatment, the rats were put on semisynthetic diets containing 20% by weight of corn oil (CO), soybean oil (SBO), crude palm oil (CPO), refined, bleached, deodorized palm oil (RBD PO) and metabisulfite-treated palm oil (MCPO) for 5 month...

Carbon-13 nuc lear m agnetic re sonance (C N MR) spe ctroscopy w as applied t o de termine the fa tty ac id positional composition of triacylglycerols in vegetable oils with oleic acid percentages “higher and lower than 50%” and with linolenic acid percentages higher than 5%. In particular, conventional C NMR spectroscopy which applies the basic one-pulse sequence for signal averaging, was used...

To date, essentially only two structural models have been proposed and debated in detail for explaining the liquid state order of triglycerides, and both invoke a form of thermotropic liquid crystalline order in triglyceride melts. These are the paralamellar model of Larsson et al. (J. Am. Oil Chem. Soc. 1992, 69, 835) and the nematic model of Cebula et al. (J. Am. Oil Chem Soc. 1992, 69, 130)....

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...

Fish oils rich in n-3 fatty acids lower plasma triglyceride profoundly but the effect on plasma cholesterol is not clear. This study tested the capacity of MaxEPA oil to modify the rise in lipoprotein cholesterol during cholesterol-rich diets. Six subjects were tested with three diets: 1) habitual (P/S 0.47, cholesterol 710 mg/d); 2) fish oil (40 g/d MaxEPA, P/S 1.62, cholesterol 190 mg/d); 3) ...

Long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency (LCHAD) is a hereditary disease referred to the group of disorders mitochondrial β-oxidation fatty acids with autosomal recessive inheritance. The main symptoms include hypoglycemia, hepatic steatosis, cardiomyopathy, cardiac arrhythmias, progressive muscle hypotension. We present case successful diagnosis and treatment long-chain use 100% m...

Vitamin K is a generic term for several fat-soluble molecules found in natural and processed foods, playing an important role human health blood coagulation bone metabolism. Although vegetable oils contain only phylloquinone (vitamin K1), milk infant formula not but also menaquinone-4 K2), which has polarity more similar to that of triglyceride impurities, therefore requiring silica gel column ...

________________________________________________________________________________ Abstract This study was performed to investigate the effects of different oils in the diets of laying quail on their performance, egg quality, serum lipids and fatty acid composition of egg yolk. One hundred and ninety two 12-wk old Japanese quail were allocated to eight groups with two replicates containing 12 qua...

Dietary fish oils are implicated in reducing the incidence of coronary heart disease, perhaps by altering the properties of plasma lipoproteins. The hypothesis that omega-3 polyunsaturated fatty acids (PUFA) in fish oils produce changes in lipid ordering and dynamics within high density lipoprotein (HDL), thereby potentially modifying cholesterol transport, is investigated here. Rabbits were fe...
