lipids play an important role in maintaining human health. thermal process cause to changes in nutritional value as well as changes in the profile of fatty acids in fish. the aim of this study was to evaluate the effect of frying on chemical composition and profile of fatty acids is fish shaary. for doing this project, 10 kg of the fish were purchased from the market of behbahan and with ice we...

The proliferation of T-lymphocytes is dependent upon their ability to synthesize and secrete the cytokine, interleukin-2, and to express cell surface receptors for interleukin-2 and transferrin. We have previously reported that certain fatty acids inhibit mitogen-stimulated T-lymphocyte proliferation. We now report that unsaturated fatty acids decrease the concentration of interleukin-2 in the ...

Three groups of Hansenula polymorpha fatty acid auxotrophic mutants were screened by their fatty acid requirement for growth. The mutants are saturated fatty acid auxotrophic mutants (Sfa), monounsaturated fatty acid auxotrophic mutants (Mfa) and polyunsaturated fatty acid auxotrophic mutants (Pfa) which required saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids...

Polyunsaturated fatty acids play an important role in human nutrition, being associated with several health benefits. The analyzed vegetables, in spite of its low fat content, lower than 2%, present a high proportion of polyunsaturated fatty acids of n-3, n-6 and n-9 series, such as α-linolenic, linoleic and oleic acids, respectively. Wild edible plants contain in general a good balance of n-6 ...

Obesity and asthma are associated, but the mechanism(s) of the association have yet to be elucidated. The aim of this study was to assess airway inflammation in relation to obesity and plasma fatty acids in males and females with and without asthma. Obese (n=68) and nonobese (n=47) adults with asthma, and obese (n=16) and nonobese (n=63) healthy controls had induced sputum and venous blood samp...

A thorough analysis of the fatty acid profiles of stipe and blade from the kelp species Laminaria hyperborea is presented. Lipid extracts were fractionated into neutral lipids, free fatty acids, and polar lipids, prior to derivatization and GC-MS analysis. A total of 42 fatty acids were identified and quantified, including the n-3 fatty acids α-linolenic acid, stearidonic acid, and eicosapentae...

The effect of alterations in dietary fat on the serum cholesterol level has been extensively studied during recent years. Numerous investigations have shown reductions in the serum lipid level of man after the dietary substitution of many vegetable oils for common animal fats or certain tropical oils such as coconut oil (1-11). The relatively high degree of saturation of coconut oil and fats of...

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...

The purpose of this study was to characterize and compare the carcass characteristics, cholesterol concentration, fatty acid composition of intramuscular fat and subcutaneous fat, and meat quality of Criollo Argentino and Braford steers reared in an extensive system, without supplementation, and slaughtered at approximately 400kg live weight. The Braford steers had greater (P<0.05) carcass weig...

In 1991, the Committee on Medical Aspects of Food Policy produced a report on the dietary reference values for food energy and nutrients for groups of people in the United Kingdom. The resulting recommendations, which included specific limits for intakes of total, saturated, trans- and cis-polyunsaturated fatty acids (PUFA) have remained a cornerstone of public health policy ever since, and sim...
