The partition ratios of radioactive fatty acids between n-heptane and a physiological buffer at 37 degrees C were measured. The fatty acids included the saturated acids with an even number of carbons from 10 to 18 and the unsaturated acids oleic, linoleic, and linolenic. In addition, the partition ratios of decanoate, myristate, and palmitate were determined over a wide pH range. Any single plo...

Over the last century, intakes of omega-6 (ω-6) fatty acids in Western diets have dramatically increased, while omega-3 (ω-3) intakes have fallen. Resulting ω-6/ω-3 intake ratios have risen to nutritionally undesirable levels, generally 10 to 15, compared to a possible optimal ratio near 2.3. We report results of the first large-scale, nationwide study of fatty acids in U.S. organic and convent...

introduction the common isoform of fatty acids in animal and herbal lipids are cis fatty acids, however in some sources such as milk and meat of ruminant, the trans fatty acids are more abundant as compared to the plant lipids. the trans fatty acids are very important because they increase the cardiovascular and heart attack. the heart disorders were increased by enhancing the concentration of ...

the aim of this work was to analyze the fatty acid profile in persian gulf shrimp, metapenaeus affinis that is one of the edible and well-known shrimps and has suitable amount of fatty acids specific polyunsaturated fatty acids (pufa). it has been reported that, a high dietary consumption of marine n-3 fatty acids may prevent the development of atherosclerosis and thrombosis. the fatty acids pr...

We report hydrogen isotopic fractionations between water and fatty acids of the sulfate-reducing bacterium Desulfobacterium autotrophicum. Pure cultures were grown in waters with deuterium (D) contents that were systematically varied near the level of natural abundance ( 37& 6 dD 6 993&). H2 of constant hydrogen isotope (D/H) ratio was supplied to the cultures. The D/H ratios of water, H2, and ...

Background Background: The fatty acid composition of the sperm membrane changes drastically during spermatogenesis and may be key to its function. Previous data has shown that intake of long chain poly-unsaturated fatty acids can change the fatty acid composition of tissues, including testes and sperm. However, whether these changes in composition translate into changes in semen quality or male...

BACKGROUND Different fatty acids may vary in their effect on the metabolic syndrome (MetS). We tested whether fatty acid classes measured in erythrocytes are associated with the MetS or its components. METHODS Included were men [n = 497; mean (SD) age, 49 (16) years] and women [n = 539; age, 48 (16) years] from 187 families in a National Heart, Lung, and Blood Institute (NHLBI) family study o...

BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with increased risk of cardiovascular disease. The purpose of this study was to investigate the ef¬fects of omega-3 fatty acids on serum paraoxonase 1 activity and lipids ratios in polycystic ovary syndrome. METHODS This double-blind randomized controlled clinical trial was conducted on 64 PCOS pa¬tients wit...

The primary products of de novo lipogenesis (DNL) are saturated fatty acids, which confer adverse cellular effects. Human adipocytes differentiated with no exogenous fat accumulated triacylglycerol (TG) in lipid droplets and differentiated normally. TG composition showed the products of DNL (saturated fatty acids from 12:0 to 18:0) together with unsaturated fatty acids (particularly 16:1n-7 and...

the effects of different cooking methods (deep fat frying, boiling and steaming) on lipid content and fatty acid composition of grass carp ( ctenopharyngodon idella ) fillets during chill storage were investigated. fillet samples were cooked and then stored at + 4°c for 4 days. the control and the cooked fillet samples were analyzed for their chemical characteristics. twelve fatty acids were id...
