the rapid expansion in world production of palm oil over the last three decades has attracted the attention of the oils and fats industry. oil palm gives the highest yield of oil per unit of any crop. palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. throughout the world, 90% of palm oil is used for edible purposes (e.g., margarine, deep fat frying...

BACKGROUND Type 2 diabetes is associated with increased plasma concentrations of non-esterified fatty acids (NEFAs), which trigger pancreatic β-cell dysfunction and apoptosis. Only long-chain saturated NEFAs induced lipotoxicity in rat insulin-producing cells in in vitro experiments, whereas unsaturated NEFAs were not toxic. Some unsaturated NEFAs even protected against lipotoxicity. In former ...

The C2 domain in protein kinase C (PKC) is homologous to equivalent domains in a number of important cytoplasmic proteins. Except for its implied function in Ca2+ and phospholipid binding, the precise role of this domain is not well understood. We examined the role of the C2 domain of PKC-alpha using a mutant enzyme in which 80% of this domain has been deleted. This mutant can be activated by p...

Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.  

INTRODUCTION The studies suggest that trans fatty acids are the most harmful type of fatty acids, and their ingestion leads to an increase in oxidative stress, changes in the plasma levels of LDL cholesterol, and a reduction in n-6 and n-3 fatty acids utilization. The objective of this study was to determine the concentration profiles of elaidic and vaccenic acids in maternal blood plasma in th...

The hexane extract of the flowers of Rheum ribes L. which was collected from north-western Iran,was obtained by Soxhlet apparatus and the essential oil composition was obtained by hydro distillationand analyzed by using GC-GC/MS. The extract from the flowers was characterized by a high amountof unsaturated fatty acids (UFA) (66.0%) and some of long chain hydrocarbon compounds. The maincomponent...

In the present investigation, 618 milk samples of Sirohi breed of goat were collected, and analyzed for conjugated linoleic acid (CLA, C18:2) and other fatty acids. The CLA in studied goat milk samples was 4.87 mg/g of milk fat and C18:2 cis-9, trans-11 contributes 2.9 mg/g of milk fat and trans10 cis12 contributes 0.82 mg/g of milk fat. The saturated fatty acids in the milk accounted for 69.55...

BACKGROUND Alcohol consumption is a major cause of fatty liver, and dietary saturated fats have been shown to protect against alcoholic fatty liver. This study investigated the mechanisms of how dietary saturated fat may modulate alcohol-induced hepatic lipid dyshomeostasis. METHODS Male Sprague Dawley rats were pair-fed with 3 isocaloric liquid diets, control, alcohol, and medium chain trigl...

The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia<...

A large number of novel fatty compounds have been synthesized by catalytic C,C-bond forming addition reactions to the C,Cdouble bond of unsaturated fatty compounds. Radical reactions such as the solvent-free addition of -halocarboxylic acid esters initiated by electron transfer, e.g., from copper to give fat-derived -lactones are described as well as Lewis acid–induced electrophilic addition re...
