This study analyzed the fatty acids composition and their profile qualitatively quantitatively of nine abundant macroalgal specimens collecting from Egyptian coasts. GC mass analysis identified 23 types, including 13 saturated (SFA) 10 monounsaturated (MUSFA). SFA dominated with 78%, while MUFAs had 22%, UFAs were negligible at 0.01%. MUSFA oleic acid (omega-9) was present in all species except...

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 ...

hydrogenation of oils might be considered as the largest reaction in the edible oil industry. the reaction consists of the addition of hydrogen at the double bounds of fatty acids. although for some reasons this might be considered a desirable reaction but for some others it might create problems in the food and nutrition chain circle due to the formation of saturated and trans fatty acids. soy...

BACKGROUND Previous data support the benefits of reducing dietary saturated fatty acids (SFAs) on insulin resistance (IR) and other metabolic risk factors. However, whether the IR status of those suffering from metabolic syndrome (MetS) affects this response is not established. OBJECTIVE Our objective was to determine whether the degree of IR influences the effect of substituting high-saturat...

Background: Liver fatty acid-binding protein (L-FABP) is the main cytosolic binding site for long chain fatty acids in hepatocytes. FABPs enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. Objectives: The aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

Earlier studies of several vegetable fats (1, 2) demonstrated that the saturated fatty acids of the triglycerides are found almost exclusivelyin the Iand 3-positions. The saturated acids in these species were predominantly palmitic and stearic. The advent of suitable gas-liquid chromatographic techniques makes possible a more detailed study of the distribution of individual fatty acids in trigl...

Since the discovery that obesity is associated with macrophage accumulation in adipose tissue,1,2 mechanisms by which adipose tissue becomes inflamed, resulting in insulin resistance, have remained elusive. Several studies have demonstrated that saturated fatty acids (SFAs) stimulate adipose tissue inflammation by a process that involves Toll-like receptor 4 (TLR4), a receptor that binds bacter...

OBJECTIVE Saturated fatty acids, such as palmitic and stearic acid, cause detrimental effects in endothelial cells and have been suggested to contribute to macrophage accumulation in adipose tissue and the vascular wall, in states of obesity and insulin resistance. Long-chain fatty acids are believed to require conversion into acyl-CoA derivatives to exert most of their detrimental effects, a r...

The effects of saturated and unsaturated fatty acids on the growth of Bordetella pertussis strain 114 in defined medium were tested. Individual fatty acids were found to be either inhibitory or stimulatory to growth, depending on concentration. Myristic (C14), pentadecanoic (C15), and palmitic (C16) acids were the most inhibitory saturated fatty acids tested. B. pertussis 114 was extremely sens...

Murine thioglycollate-elicited peritoneal macrophages were cultured in the presence of a variety of fatty acids added as complexes with bovine serum albumin. All fatty acids tested were taken up readily by the cells and both neutral and phospholipid fractions were enriched with the fatty acid provided in the medium. This generated a range of cells enriched in saturated, monounsaturated or polyu...
