Fatty acids can be divided into four general categories: saturated, monounsaturated, polyunsaturated, and trans fats. Saturated fatty acids and trans fats are associated with an increased risk of coronary heart disease. Monounsaturated fatty acids and polyunsaturated fatty acids are associated with a decreased risk of coronary heart disease, although these associations are not uniformly support...

Dietary sources of the essential fatty acid a-linolenic acid (ALA; 18:3n-3) include green leaves, some seeds, nuts and cooking oils. The principal dietary source of the long-chain (LC) n-3 polyunsaturated fatty acids (PUFA) eicosapentaenoic acid (EPA; 20:5n-3), docosapentaenoic acid (DPA; 22:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) is oily fish, yet it is estimated that only 27% of UKadult...

The essential nature of n 3 polyunsaturated fatty acids in neurological development Neural membrane aminophospholipids are characterized by high concentrations of n-3 polyunsaturated fatty acids (PUFA), particularly docosahexaenoic acid (C22:6n-3). For example, adult human cerebral cortex phosphatidylethanolamine (PE) contains 30.5% C22:6n-3 while C22:6n-3 in the retina accounts for 22.2% of PE...

This is the first report on the effects of a single bout of swimming to exhaustion in cold water on rat erythrocyte deformability, aggregation and fatty acid composition in erythrocyte membranes. The results indicate that there was a significant decrease in body temperature of experimental rats swimming in water at 4 degrees C and 25 degrees C when compared to the control. Erythrocyte aggregati...

OBJECTIVES N-3 polyunsaturated fatty acids have been proposed as a novel treatment for preventing postoperative atrial fibrillation due to their potential anti-inflammatory and anti-arrhythmic effects. However, randomized studies have yielded conflicting results. The objective of this study is to review randomized trials of N-3 polyunsaturated fatty acid use for postoperative atrial fibrillatio...

Nutritional value of freshwater mesozooplankton, fatty acid (FA) and amino acid (AA) compositions were determined in the middle of each season for a one-year period from May 2009 to February 2010 in Hanna Dam Lake, Isfahan, Iran. FA and AA composition significantly (P<0.05) varied in relation to the seasonal changes of water quality, phytoplankton and zooplankton community. The content of satur...

The aim of the present study was to assess the effect of slaughter and carcass weight, age at slaughter and sex on the fatty acid profile of the Greek Boutsiko sheep breed. Twenty lambs (ten females and ten males) were examined. The lambs were slaughtered at the age of 48 days. Carcasses were chopped in nine specific cuts and a random sample of 100 g was taken from each cut, with a total of 180...

The effect of marine polyunsaturated fatty acids on biofilm formation by the human pathogens Candida albicans and Candida dubliniensis was investigated. It was found that stearidonic acid (18:4 n-3), eicosapentaenoic acid (20:5 n-3), docosapentaenoic acid (22:5 n-3) and docosahexaenoic acid (22:6 n-3) have an inhibitory effect on mitochondrial metabolism of both C. albicans and C. dubliniensis ...

The objective of this study was to determine if children with phenylketonuria (PKU) have lower fatty acid concentrations in total erythrocyte lipid due to the phenylalanine restricted diet therapy compared to healthy control subjects. Dietary intake and fatty acid concentrations in total erythrocyte lipid were measured in twenty-one subjects (</=6 years of age) with PKU and twenty-three control...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P < 0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fa...
