1. Phosphatidylinositol (PI) is a minor component of lung surfactant which may be able to replace the functionally important phosphatidylglycerol (PG) [Beppu, Clements & Goerke (1983) J. Appl. Physiol. 55, 496-502] without disturbing lung function. The dipalmitoyl species is one of the main species for both PI (14.4%) and PG (16.9%). Besides the C16:0--C16:0 species, the C16:0--C18:0, C16:0--C1...

To improve beef quality, a selection of specific breeds for crossbreeding, genotyping, and candidate genes in breeding animals can be some the solutions. The objective this study was to determine effects FASN, SCD, GH on carcass fatness fatty acid (FA) composition intramuscular lipids crossbred Holstein × (Simmental, Belgian Blue, Limousin, Piemontese). allelic genotypic distribution polymorphi...

In order to study the effect of grazing pastures with a different botanical composition on rumen and intramuscular fatty acid metabolism, 21 male lambs were assigned to three botanically different pastures: botanically diverse (BD) (consisting for 65% of a variety of grass species); Leguminosa rich (L) (consisting for 61% of Leguminosae) and intensive English ryegrass (IR) (with 69% Lolium pere...

A 4 x 5 Youden square design was used to determine the effects of form of oil and roasting temperature of soybeans on site and extent of OM, fiber, energy, lipid, and fatty acid digestion and the degree of ruminal biohydrogenation of C18 unsaturated fatty acids. Four steers (373 kg +/- 30.7) with ruminal, duodenal, and ileal cannulas were fed each of five diets during five periods. Diets contai...

The Bordeaux grape variety is the most used in production of red juices. objective work was to evaluate carotenoids, flavonoids, vitamins C, E and B complex, total fatty acids, phytates, tannins, antioxidant capacity, phenolic compounds centesimal composition whole (W) defatted (D) seed flours oil (O). Total acids were evaluated by gas chromatography (flame ionization detector). Analysis comple...

Based on the most common vegetable oil blends, binary and ternary analytical mixtures were constructed in mass fractions from 0.50 to 0.97, their fatty acid profile was determined represented graphically. The acids with discriminatory power selected construct equations predict commercial blend proportions. Three different linear resulted analysis for i. palm oil-based blends: y = (0.3713 ± 0.02...

The objective of this study was to examine the effect of oleic (OA), linoleic (LA) and α-linolenic (ALA) acid used as supplements (3.5% wt/wt) to a diet containing 80% lucerne and 20% barley on rumen fermentation and lipid metabolism in an artificial rumen (Rusitec). The experiment lasted 12 days with 6 days of stabilization period. The fatty acid (FA) supplementation to a mixed diet did not af...

Lysophophatidylcholine (LysoPC) is an abundant constituent in human plasma. Patients with malignant cancer diseases have attenuated LysoPC plasma levels, and thus LysoPC has been examined as a metabolic biomarker for cancer prediction. Preclinical studies have shown that solid tumor cells drastically degrade LysoPCs by incorporating their free fatty acids into cell membrane phospholipids. In th...

The effect of conjugated linoleic acid (CLA) feeding on growth performance and fatty acid profiles in thigh meat of broiler chicken was investigated using meta-analysis with a total of 9 studies. Overall effects were calculated by standardized mean differences between treatment (CLA fed) and control using Hedges's adjusted g from fixed and random effect models. Meta-regression was conducted to ...

In a previous work [Heinz, Castelijns, and Suter, J. Am. Chem. Soc. 115, 9500 (2003)], we developed an accurate force field and simulated the phase transitions in C18-mica (octadecyltrimethylammonium-mica) as well as the absence of such transitions in 2C18-mica (dioctadecyldimethylammonium-mica) between room temperature and 100 degrees C. Here we analyze (i) average z coordinates of the carbon ...
