pythium irregulare oomycetes adapts with environmental changes including crude oil concentration by changing the composition of lipids in the cytoplasmic membrane and providing the required characteristics for adaptation in improper and stressful environmental situations. it was found that cultivation of pythium irregulare lx oomycetes in the nutrient media with different concentrations of crud...

Background: Fatty acids are the main compounds in edible oils. Oil thermal stability depends on the composition of fatty acids. So, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process.  Methods: Totally, eight virgin olive oil samples, including five imported oils from market place of Ma...

Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...

the aim followed in this study was to make a comparison of the composition of fatty acids available in the sperm lipids of cattle, sheep and goat. semen samples were collected from 28 holestein cows, 12 chal rams and 7 mahabadi goats. after washing out and removal of the seminal plasma, total lipids of the sperm were extracted and fatty acids trans-methylated. the fatty acid methyl esters were ...

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...

The proximate composition, amino acid and fatty acid composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker (Pseudosciaena crocea) were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but lowest lipid content. Offshore cage-cultured fish showed significantly higher content of moisture and ...

In a study with 52 healthy volunteers, the effect of different amounts of co3 fatty acids on the blood lipid composition was investigated. Doses of 1.4, 2.3, 4. 1, and 8.2 g of w3 fatty acids were administered to these subjects daily over a period of 4 wk. Total cholesterol, highdensity hipoprotein cholesterol, total triglycerides, and glucose were determined in blood serum and hemoglobin in wh...

background & aim: ocimum basilicum l. is belong to the lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. the seed of this plant is rich in poly un-saturated fatty acids (pufa) and produced a large amount of mucilage. experimental: the oil of seed was extracted separately and converted to fatty acids methyl esters...

chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

Objectives: The objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of Ligularia persica Boiss (L. persica) growing wild in north of Iran. Materials and Methods: Essential oils were extracted by using Clevenger-type apparatus. Antibacterial activity was tested on two Gram-positive and two Gra...
