Most studies on lipid lowering diets have focused on the total content of saturated, polyunsaturated and monounsaturated fatty acids. However, the distribution of these fatty acids on the triacylglycerol (TAG) molecule and the molecular TAG species generated by this stereospecificity are characteristic for various native dietary TAGs. Fat randomization or interesterification is a process involv...

Recent advances in gas-liquid chromatography have permitted the separation and identification of aldehydes derived from plasmalogens, and a number of analyses of aldehydes from animal plasmalogens have been reported (l-3). Bacterial plasmalogens, on the other hand, have only recently been discovered, and no analyses of their fatty aldehydes are available (4-6). Such analyses would be of particu...

A comparative study was conducted to see the mutational analysis for monounsaturated fatty acids in rapeseed (Brassica napus L.) mutant populations. By using gamma irradiation, a range of variability generated for oil content and fatty acid composition in rapeseed seeds. The induced genetic variability was analyzed for two consecutive years in two contrasting environments at elevations of 510 a...

Fatty acid composition of fish is one of the key factors for the evaluation of fish nutritional value and it could be different based on fish species, habitat, nutrition and etc. The aim of the present study was to evaluate the fatty acid composition of five commercially important freshwater fish from the fish market. Studied fish were as follows: Barbell, Luciobarbus pectoralis (Heckel, 1843),...

objectives the link between dietary fat and heart disease has been established for decades. although, the atherogenic effect of saturated fatty acids is somehow controversial, the cardioprotective effects of polyunsaturated fatty acids (pufa) are clearly documented. this study investigated the effects of different dietary oils on serum fatty acid composition in rat. methods six week male wistar...

The influence of lipids on gap-junction-mediated intercellular communication (i.e., metabolic cooperation) between Chinese hamster V79 cells was investigated. Unsaturated free fatty acids (oleate, linoleate, linolenate, palmitoleate, myristoleate, and arachidonate) inhibited metabolic cooperation between 6-thioguanine-resistant, hypoxanthine guanine phosphoribosyltransferase-deficient and 6-thi...

The Fatty acid content and composition of fixed oil from Zanthoxylum rhetsa seeds was determined. The seeds were found to contain about ~19.5% of crude fixed oil on a dry weight basis. Fatty acids were converted into methyl esters and analyzed by GC-FID. Ten fatty acids were identified using GC-FID. The major monounsaturated and saturated fatty acids were oleic acid (41.6 43.5%) and palmitic ac...

Genetic parameters for eating quality assessed by trained taste panellists were estimated on longissimus thoracis et lumborum (LTL) muscle in Scottish Blackface lambs, comprising lines previously divergently selected for carcass lean content (FAT and LEAN lines) as well as crosses between these lines. Also, relationships between eating quality assessments and fatty acid composition were investi...

The production of fatty acids in cream containing one of the three probiotic microorganisms (Bifidobacterium lactis, Lactobacillus acidophilus and Lactobacillus rhamnosus) was evaluated at 4±1 °C for up to 15 days. Gas chromatographic analysis of the fatty acid content showed that during storage the amount of linoleic and α-linolenic acids increased in the probiotic cream fermented with B. lact...

Dietary fats have important effects on the risk of cardiovascular disease (CVD). Abundant evidence shows that partial replacement of saturated fatty acids (SAFA) with unsaturated fatty acids improves the blood lipid and lipoprotein profile and reduces the risk of coronary heart disease (CHD). Low-fat diets high in refined carbohydrates and sugar are not effective. Very long-chain polyunsaturate...
