We assessed the presence of fatty acid (FA)-sensing mechanisms in hypothalamus of Senegalese sole (Solea senegalensis) and investigated their sensitivity to FA chain length and/or level of unsaturation. Stearate (SA, saturated FA), oleate (OA, monounsaturated FA of the same chain length), α-linolenate [ALA, a n-3 polyunsaturated fatty acid (PUFA) of the same chain length], and eicosapentanoate ...

In numerous studies charge remote fragmentation (CRF) has been shown to be a powerful technique for determination of primary structure by allowing location of double bonds, various functional groups, and branching in a variety of compound types directly by mass spectrometry. Instrumentation and ionization methods traditionally used for CRF, however, are becoming rare, in large part because ESI ...

BACKGROUND/AIMS The activation of acid sphingomyelinase by cellular stress or receptors or the de novo synthesis lead to the formation of ceramide (N-acylsphingosine), which in turn modifies the biophysical properties of cellular membrane and greatly amplifies the intensity of the initial signal. Ceramide, which acts by re-organizing a given signalosome rather than being a second messenger, has...

In recent years there is growing interest on the role of long chain omega-3 polyunsaturated fatty acids (omega-3 LC-PUFA) in pregnancy and the growth and development of the offspring. We aim to characterize and provide baseline data on the intake of LCPUFA (omega-3 and omega-6) in a prospective cohort of 829 pregnant Indian women and report associations between LCPUFA intake and erythrocyte mem...

Human primary hepatocytes are the gold standard for investigating lipid metabolism in nonalcoholic fatty liver disease (NAFLD); however, due to limitations including availability and donor variability, the hepatoma cell lines Huh7 and HepG2 are commonly used. Culturing these cell lines in human serum (HS) has been reported to improve functionality; however, direct comparison of fatty acid (FA) ...

Metabolic engineering of microalgae to accumulate high levels of medium chain length fatty acids (MCFAs) has met with limited success. Traditional approaches employ single introduction of MCFA specific acyl-ACP thioesterases (TEs), but our current research in transgenic Dunaliella tertiolecta line has highlighted that, there is no single rate-limiting approach that can effectively increase MCFA...

Functional breads constitute an interesting alternative as vehicle of new essential fatty acids sources. The aim of this study was to improve the fatty acids (FA) profile of bakery products, producing breads with low saturated fatty acid (SFA) content and with high polyunsaturated fatty acid (PUFA) content, through partial substitution of wheat flour by other ingredients (soy flour, flax flour,...

Human papilloma virus-induced recurrent laryngeal papillomatosis is considered a troublesome and dangerous disease, because it can cause airway obstruction. Better understanding of metabolic pathways followed under pathological conditions can contribute to improved therapies by which growth and recurrence may be obviated. Part I of this study presents a clinically relevant total lipid fatty aci...

Abstract Feed is the main factor impacting composition and quality of milk dairy animals. Therefore, present review explores effects feed nutrition on fat content levels healthy fatty acids (FA) in consumed by humans. Milk products are two sources unhealthy FA human nutrition. The concentrations depend mainly diets; therefore, ratios can be greatly altered some feeding strategies. Dietary suppl...

This study was designed to evaluate biochemical changes in the fatty acid (FA) compositions of selected lipid depot (kidney and liver) and absorption (intestine) organs in larvae and metamorphosing sea lamprey, Petromyzon marinus. Palmitic or stearic acids were generally the predominant saturated fatty acids (SFA) before and during metamorphosis, but the greatest proportion of myristic acid occ...
