milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...

The anecdote "we are what we eat" in line with the doctrine of Hypocrates in 400 BC “Let food be thy medicine and medicine thy food” are vividly portray the importance of daily regimen in human health and body well-functioning. There is a growing body of evidence that suggests the relative intake of specific nutrients can have a profound effect on physiology of individuals...

Numerous investigations have led to the point at which refined enzyme systems may be used to study the biosynthesis of saturated fatty acids (2, 3). The biosynthesis of unsaturated fatty acids has not been so thoroughly elucidated. Formation of unsaturated fatty acids has been observed experimentally in viva (4-9) and in vitro (10, 11) but several of these studies showed that incorporated radio...

Sterol regulatory element-binding protein-1c (SREBP-1c) enhances transcription of genes encoding enzymes of unsaturated fatty acid biosynthesis in liver. SREBP-1c mRNA is known to increase when cells are treated with agonists of liver X receptor (LXR), a nuclear hormone receptor, and to decrease when cells are treated with unsaturated fatty acids, the end products of SREBP-1c action. Here we sh...

Both cis- and trans-unsaturated but not saturated fatty acids activated protein kinase C purified to apparent homogeneity from rat brain. Fatty-acid-induced enzyme activation was not more than additive with that by phospholipids and was potentiated by diacylglycerol. Recently, we demonstrated that cis- and trans-unsaturated fatty acids induced platelet aggregation and phosphorylation of specifi...

Abnormal high density lipoprotein metabolism may contribute to the increased atherosclerosis associated with diabetes and insulin resistance. The ATP-binding cassette transporter ABCA1 mediates cholesterol transport from tissue macrophages to apoA-I, the major high density lipoprotein protein component. Because fatty acids are elevated in diabetes, we examined the effects of fatty acids on ABCA...

Background: This study was carried out to determine the oil content and of fatty acids in stem, leave and seed of halophyte plant (Suaeda vermiculata ) locally called “Tahma” growing along the shorelines of the Persian Gulf in Bushehr Province. Material and Methods: The total oil and fatty acid contents of leaves, stem and root were extracted in n-hexane using Soxhlet and the fatty acid composi...

We introduced efficient incorporation of unsaturated fatty acids into volicitin [N-(17-hydroxylinolenoyl)-L-glutamine] and N-linolenoyl-L-glutamine, insect-derived elicitors of plant volatiles, in the common cutworms Spodoptera litura by the incubation of larval gut tissues with unsaturated (linolenic, linoleic, and oleic acids) or saturated fatty acids (palmitic and stearic acids) sodium salt,...

Low and high intake of fat consumption regardless of its kind can jeopardize personal and public health. Despite the importance of quality and quantity of fat in the diet and its relationship with some chronic disorders such as coronary heart disease, some types of cancers, obesity and diabetes, the consumption pattern of fats and their . constituent fatty acids have not yet been assessed in ou...
