Effect of eicosatetraynoic acid on liver and plasma lipids
Lipids - Tập 17 - Trang 763-770 - 1982
Groups of rats were fed a fat-free diet supplemented with 0.5% safflower oil (control) or the control diet containing 0.5% of 5,8,11,14-eicosatetraynoic acid (TYA). Blood was collected weekly and plasma lipids analyzed. After 4 weeks, the animals were killed and the liver lipids were analyzed in detail. The acetylenic fatty acid perturbed plasma neutral lipid and phospholipid class concentrations ...... hiện toàn bộ
Nonalcoholic components in wine reduce low density lipoprotein cholesterol in normocholesterolemic rats
Lipids - Tập 36 - Trang 383-388 - 2001
Using an experimental model that enables the effects of alcohol to be distinguished from the effects of the nonalcoholic components present in wine, we determined whether wine has effects other than those of alcohol on the metabolism of cholesterol. Male rats were fed a standard diet and had free access to water and either wine or an equivalent alcohol solution for 45 d or 6 mon. Alcohol intake wa...... hiện toàn bộ
Comparative studies on the fatty acid composition of moderately and extremely thermophilic bacteria
Lipids - Tập 9 - Trang 476-480 - 1974
The fatty acids of three strains of extremely thermophilic bacteria and three strains of moderately thermophilic bacteria were examined by gas liquid chromatography. All the thermophiles contained straight, iso, and ante-iso branched fatty acids. Iso C17∶0 acid was abundant in both the moderately thermophilic strains (10–33%) and the extremely thermophilic strains (50–61%). The pair of fatty acids...... hiện toàn bộ
n−3 Polyunsaturated fatty acids and inflammation: From molecular biology to the clinic
Lipids - Tập 38 - Trang 343-352 - 2003
The immune system is involved in host defense against infectious agents, tumor cells, and environmental insults. Inflammation is an important component of the early immunologic response. Inappropriate or dysfunctional immune responses underlie acute and chronic inflammatory diseases. The n−6 PUFA arachidonic acid (AA) is the precursor of prostaglandins, leukotrienes, and related compounds that hav...... hiện toàn bộ
Assessment of the arachidonic acid content in foods commonly consumed in the American diet
Lipids - Tập 33 - Trang 1151-1157 - 1998
Arachidonic acid (AA) is an extremely important fatty acid involved in cell regulation. When provided in the diet, it is cogently incorporated in membrane phospholipids and enhances eicosanoid biosynthesis in vivo and in vitro; however, controversy exists as to the levels of AA in food and in the diet. This study determined the amount of AA in cooked and raw portions of beef (rib eye), chicken (br...... hiện toàn bộ
Ring position in cyclopropene fatty acids and stearic acid desaturation in hen liverAbstract Four cyclopropene fatty acids, having the double bond of the cyclopropene ring at the 8,9, 9,10, 10,11 and 11,12 positions, respectively, were tested as inhibitors of stearic acid desaturation by the desaturase enzyme system of hen liver. The first three were powerful inhibitors, but the last was not. The cyclopropene acids with the 9,10 and 10,11 double bo... ... hiện toàn bộ

Three Hen Strains Fed Photoisomerized trans,trans CLA-Rich Soy Oil Exhibit Different Yolk Accumulation Rates and Source-Specific Isomer Deposition
Lipids - Tập 50 - Trang 397-406 - 2015
Most CLA chicken feeding trials used cis,trans (c,t) and trans,cis (t,c) CLA isomers to produce CLA-rich eggs, while reports of trans,trans (t,t) CLA enrichment in egg yolks are limited. The CLA yolk fatty acid profile changes and the 10–12 days of feeding needed for maximum CLA are well documented, but there is no information describing CLA accumulation during initial feed administration. In addi...... hiện toàn bộ
Analysis of triglycerides using atmospheric pressure chemical ionization mass spectrometry
Lipids - Tập 30 - Trang 173-175 - 1995
Atmospheric pressure chemical ionization (APCI) mass spectrometry was investigated as a new method for analysis of a mixture of triglycerides separated by reverse-phase high-performance liquid chromatography. A mixture of homogeneous (monoacid) triglyceride standards containing fatty acids with zero to three double bonds was analyzed to demonstrate the quality of mass spectra obtained by using the...... hiện toàn bộ
Lipoprotein lipid and protein synthesis in experimental nephrosis and plasmapheresis. I: Studies in rat in vivo
Lipids - Tập 14 - Trang 695-702 - 1979
The incorporation of L-4,5-[3H]leucine into the ultracentrifugally separated apolipoproteins of very low, low, and high density lipoproteins (VLDL, LDL, HDL) and into serum albumin was found three-to four-fold higher in nephrotic than in normal rats one hour after intravenous injection. Incorporation of leucine into the circulating lipids was negligible. Increases of similar magnitude were obtaine...... hiện toàn bộ
