Phospholipid acyl turnover was assessed in mouse peritoneal exudate cells which consisted primarily of macrophages. The cells were incubated for up to 5 h in media containing 40% H218O, and uptake of 18O into ester carbonyls of phospholipids was determined by gas chromatography-mass spectrometry of hydrogenated methyl esters. The uptake was highest in choline phospholipids and phosphatidylinosi...
Highly purified chromaffin granule ghosts contain about 100 (89.1-110.2, n = 8) nmol of long-chain free fatty acids/mg of protein. About 40% of the fatty acids were mono- and polyunsaturated, of which arachidonate accounted for approximately 20%. Incubation with fatty acid-free bovine serum albumin selectively depleted the ghosts of unsaturated fatty acids. The effect of a series of long-chain ...
prostate cancer is the most common cancer in america and canada, and is the sixth most common cancer worldwide. dietary factors play an important role in prostate cancer development; one of them is dietary fat, particularly pufa intake. thus, this study aimed to review the current articles on the correlation between pufa and prostate cancer. we searched the pubmed database, and selected article...
two omega-3 fatty acids including docosahexaenoic acid (dha) and eicosapentaenoic acid (epa) are essential for the physiologic function of neuronal cell membrane. normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine-in...
Background and objectives: High consumption of trans fatty acids is associated with increased risks cardiovascular diseases, insulin resistance, lipid disorders, diabetes, and possibly cancer. Therefore, most developed countries produce food products with trans fatty acid content of 0%-2% to support the consumers. This study sought to determine the amount of fatty acids in meat products and keb...
Free fatty acids (FFA), the uranyl ion, and the basic dye Rhodamine B form colored complexes, which are extractable into toluene or benzene. Fatty acids of different chain lengths above C(10) and different degrees of unsaturation gave constant molar yield. Complexes in toluene alone are unstable, especially in the light, but a small amount of aqueous uranyl acetate stabilizes them sufficiently ...
Fatty acids are important molecules with multiple biological properties. Emerging evidence suggests that fatty acids can modulate autophagy. Saturated fatty acids contribute to pancreatic β-cell dysfunction in type 2 diabetes. Palmitic acid, one of the long-chain saturated fatty acids (LCFA), induces autophagy of β-cells which protects them from dysfunctions and apoptotic cell death. Short-chai...
etabolic adaptation likely represents one of the earliest esponses to myocardial ischemia. The myocardium preferntially oxidizes free fatty acids for energy production. owever, the dependency of fatty acid metabolism on xygen makes this process particularly vulnerable to ischeia. Under hypoxemic or ischemic conditions, the energy equirements of the myocardium are met by glucose rather han free ...
As part of a collaboration with the National Institutes of Health's Office of Dietary Supplements and the Food and Drug Administration's Center for Drug Evaluation and Research, the National Institute of Standards and Technology has developed two standard reference materials (SRMs) representing different forms of saw palmetto (Serenoa repens), SRM 3250 Serenoa repens fruit and SRM 3251 Serenoa ...
