background and objectives: probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesi...

since long term dietary fatty acide intake is reflected in the fatty acide composition of  Adipose tissue, this study was aimed to compare the adippose tissue fatty acide profile of angiography documented CAD (test)and non-CAD(control)  patients.the first group were 25 patients who underwent coronary artery bypass graft surgery in open heart surgery section of Shahid Beheshti hospital of Kerman...

Background and Objectives: Oils used in frying should include special characteristics such as high oxidative stability, prolonged shelf life, low price, abundance and availability and desirable flavors. Nowadays, consumers are further interested in low saturated frying oils.  Recently, manufacturers focus on eliminating palm oil derivatives (as a major vegetable source of saturation) from fryin...

The effects of free fatty acids on rat liver phosphoenolpyruvate carboxykiuase (EC 4.1.1.32), pyruvate carboxylase (EC 6.4.1. I), and glucose 6-phosphatase (EC 3.1.3.9) were determined to evaluate the suggestion that free fatty acid inhibition of key glycolytic enzymes constitutes a specific inhibitory effect. Activities of ah of these gluconeogenie enzymes were found to be markedly inhibited b...

The effect of electrical stimulation of various hypothalamic regions on levels of plasma free fatty acids, glucose, triglycerides, and cholesterol was studied in fasted cats. Appreciable changes were observed in plasma free fatty acids and glucose but not in plasma triglycerides or cholesterol. These changes appeared to be dependent upon small differences in the placement of electrodes and coul...

A description is given of a new method for determining free fatty acids in blood plasma. The free fatty acids are extracted from the plasma, transferred to heptane and washed with H2SO4 (O.OlN). The earlier two-phase tritration procedure is now performed in a one-phase medium by means of an autoburette using tetrabutylammoniumhydrcxide. A curve, simultaneously recorded by means of a compensatio...

Body fat deposition and excess free fatty acid (FFA) metabolism contribute to dyslipidemia and the adverse health consequences of obesity. Individuals with upper body obesity have impaired functioning of adipocytes, the primary fatty acid storage site. Excess visceral fat is strongly associated with impaired suppression of FFA release in response to insulin, as well as with hypertriglyceridemia...

I HE MICIIODETERMIXATION of fiee fatt acids (FFA) in plasma has received colisiderable attelition in recent years (1-8). Although a riumher of different procedures Ilave beemi reported, most of them consist of 2 essential steps: tire extraction of tire FFA from plasnla with orgamlic solvents, an(1 the titration of the extracted FFA in a 2-phase system with a standard aqueous base. Various extra...

Fatty acids are known to possess antibacterial, antimalarial and antifungal activity. The development of resistance of microbes, including fungi and yeasts, towards antimicrobial agents already in use, necessitates the search for alternative antimicrobials, including fatty acids and their derivatives (e.g. methylated and hydroxyl fatty acids). Although fatty acids may not be as effective as che...

UNLABELLED Recent studies have identified a cholestatic variant of nonalcoholic fatty liver disease (NAFLD) with portal inflammation and ductular reaction. Based on reports of biliary damage, as well as increased circulating free fatty acids (FFAs) in NAFLD, we hypothesized the involvement of cholangiocyte lipoapoptosis as a mechanism of cellular injury. Here, we demonstrate that the saturated ...
