background: co-supplementation of unsaturated fatty acids (fas) with saturated fas may decrease the adverse effects of saturated fa-induced lipotoxicity. the objective of the present study was to evaluate the effect of palmitoleic acid (unsaturated fatty acid) on palmitic acid (saturated fatty acid) induced lipotoxicity criteria in the primary culture of adult rat cardiomyocytes. methods: cells...

During the complete oxidation of fatty acids, the electrons removed from fatty acids in different forms (FADH2 and NADH2) pass through the respiratory chain, driving the ATP synthesis. Generally, the ATP yield due to the complete oxidation of fatty acids is calculated by sum total the ATPs obtained due to the oxidation of FADH2 and NADH2 due to lack of any particular method. This calculation is...

The formation of long chain unsaturated fatty acids from the corresponding saturated acids in animals was established by the work of Schoenheimer and Rittenberg (1) and Stetten and Schoenheimer (2). Recent studies in this laboratory have shown that in yeast the formation of Ag-unsaturated fatty acids is catalyzed by an enzyme system acting on the coenzyme A derivatives of the corresponding satu...

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...

BACKGROUND The health benefits of increased intakes of omega-3 fatty acids are well established but palatability often presents a problem. The process of emulsification is used in the food industry to provide a wider spectrum of use, often with the result of increased consumption. Moreover, as emulsification is an important step in the digestion and absorption of fats, the pre-emulsification pr...

The fatty acid growth requirements of a sterol-requiring Mycoplasma (strain Y), unable to synthesize or alter the chain length of either saturated or unsaturated fatty acids, were investigated. In some cases adaptation was required for growth when mycoplasmas were transferred to media of differing fatty acid composition. No straight-chain saturated acid supported growth when tested alone, but g...

BACKGROUND Hydrogen peroxide (H2O2) is an oxidant agent and this molecule naturally occurs in the body as a product of aerobic metabolism. Geraniol is a plant-derived natural antioxidant. The aim of this study was to determine the role of geraniol on hepatic fatty acids alterations following H2O2-induced oxidative stress in male rats. METHODS After randomization, male Wistar rats were divided...

It is the position of the Academy of Nutrition and Dietetics (the Academy) that dietary fat for the healthy adult population should provide 20% to 35% of energy, with an increased consumption of n-3 polyunsaturated fatty acids and limited intake of saturated and trans fats. The Academy recommends a food-based approach through a diet that includes regular consumption of fatty fish, nuts and seed...

We tested whether trans fatty acids and saturated fatty acids had different effects on flow-mediated vasodilation (FMD), a risk marker of coronary heart disease (CHD). Consumption of trans fatty acids is related to increased risk of CHD, probably through effects on lipoproteins. Trans fatty acids differ from most saturated fatty acids because they decrease serum high-density lipoprotein (HDL) c...

Dietary lipid composition profoundly influences the hibernation pattern of the chipmunk Eutamias amoenus. The object of the present study was to investigate whether these physiological changes following feeding of saturated and unsaturated lipids were associated by compositional changes of fatty acids of tissues and membranes. Animals were fed with rodent chow (control diet), rodent chow with 1...
