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...

Sesamin is known as a specific inhibitor of delta 5-desaturation, the conversion from dihomo-gamma-linolenic acid (20:3(n=6)) to arachidonic acid (20:4(n-6)). In the previous paper, we reported that sesamin inhibited delta 5-desaturation of n-6 fatty acids in rat hepatocytes but not that of n-3 fatty acids, from 20:4(n-3) to 20:5(n-3). Then, we studied the effects of sesamin on delta 5-desatura...

BACKGROUND Polyunsaturated fatty acid intake favorably affects chronic inflammatory-related diseases such as cardiovascular disease; however, high intake of n-6 fatty acids may attenuate the known beneficial effects of n-3 fatty acids. METHODS AND RESULTS We investigated habitual dietary n-3 fatty acid intake and its interaction with n-6 fatty acids in relation to the plasma inflammatory mark...

Background: Many studies are being conducted to improve the quality of bull sperm in storage conditions. It seems that increasing sperm membrane unsaturated fatty acids can enhance sperm quality. This study was aimed to investigate the effects of combination of omega- 3, 6, 9 fatty acids on characteristics of bovine chilled semen. Materials and Methods: Different levels of oil containing omega-...

Pistachio nut has high nutritional value. The fat and protein are the common part of pistachio. Major part (about 88%) of the fat content of pistachio includes unsaturated fatty acids. Unsaturated fatty acids are known to have positive effects on human health like preventing to heart diseases. This research has evaluated protein, fat and fatty acids content of some commercial pistachio cultivar...

To investigate the importance of factors influencing the fatty acid composition, lipid and lipoprotein metabolism in the rat, the effect of 3-thia fatty acids of chain-length ranging from octyl- to hexadecylthioacetic acid were studied. In liver, very low density lipoprotein (VLDL), and low density lipoprotein (LDL), the hypolipidemic 3-thia fatty acids, namely C12-S-acetic acid to C14-S-acetic...

A comparison was made between the liver and brain conversion of linoleic acid, 18:2n-6, and linolenic acid, 18:3n-3, to long chain polyunsaturated fatty acids in domestic felines. This report demonstrates that 6-desaturase activity does exist in the feline. The liver produced deuterium-labeled polyunsaturated fatty acids up to 22:4n-6 and 22:5n-3. The brain was found to accumulate the deuterium...

Anti-Pasteurella pestis factor (APF) inhibited bacterial growth, but there was no evidence that APF from either mouse or guinea pig or selected fatty acids physically disrupted the cell wall. The fatty acids selected were representative of those found in APF. APF inhibited oxidation of beta-d-glucose but not oxidation of glucose-6-phosphate, whereas fatty acids inhibited the oxidation of glucos...
