Free Fatty Acids of Human Meconium
Neonatology, 1986Meconium samples of 20 healthy full-term babies were analyzed for free fatty acid content. The total fatty acid content per net weight varied by as much as 9-fold between samples. Considerable variability was also observed in the individual fatty acids found in each sample.

Free fatty acids and insulin resistance
Current Opinion in Clinical Nutrition and Metabolic Care, 2007Dysregulation of free fatty acid metabolism is a key event responsible for insulin resistance and type 2 diabetes. According to the glucose-fatty acid cycle of Randle, preferential oxidation of free fatty acids over glucose plays a major role in insulin sensitivity and the metabolic disturbances of diabetes mellitus.

Plasma free fatty acids in exercise
Journal of Applied Physiology, 1964The effects of exercise of different intensity and duration on plasma free fatty acids (FFA), blood glucose, and lactate were investigated in eight healthy young men. In heavy 10-min work the blood lactate rose rapidly and the FFA decreased. Blood sugar showed no marked change.

Free fatty acid profiles in preeclampsia
Prostaglandins, Leukotrienes and Essential Fatty Acids, 2009Preeclampsia has many characteristics similar to the metabolic syndrome. One of these is aberrant lipid metabolism. We studied free fatty acid (FFA) profiles at baseline and after oral glucose load in 21 preeclamptic and 11 normotensive pregnant women. Insulin sensitivity was measured by intravenous glucose tolerance test. We found that serum total FFA

Biochemistry of radioiodinated free fatty acids
Molecular and Cellular Biochemistry, 1989Radioiodinated free fatty acids have been developed to study myocardial metabolism non-invasively in man. In the present study the distribution of radiolabeled lipids in the myocardium and in arterial and coronary sinus blood was evaluated following injection of three commonly used iodinated fatty acids in fasted (n = 5) and lactate loaded (n = 3) dogs.

Abstract Here we describe the analysis of plasma free fatty acids (FFA) only, because the measurement of fatty acids in neutral lipids, phospholipids, and total lipids has already been well documented. Plasma FFA can, furthermore, be produced by oxidatively damaged tissues because hydrolysis of phospholipids is stimulated by oxidative ...

Bioluminescent determination of free fatty acids
Analytical Biochemistry, 1984A simple, highly specific, and sensitive bioluminescent method for determination of free fatty acids in unextracted plasma or serum has been developed. The method is based on the activation of free fatty acids by acyl-CoA synthetase (EC 6.2.1.3). The pyrophosphate formed is used to phosphorylate fructose 6-phosphate in a reaction catalyzed by the ...

Inhibition of fatty acid mobilization by arterial free fatty acid concentration
Acta Physiologica Scandinavica, 1986Subcutaneous, inguinal adipose tissue from dogs was perfused with blood in which the free fatty acid (FFA) concentration was varied corresponding to FFA/albumin molar ratios between 1 and 6. Otherwise the composition of the perfusate was kept constant. In order to stimulate lipolysis, isoprenaline and theophyllamine were added to the perfusate. A raise

Chylomicrons are cleared from plasma into fat depots by the action of the enzyme lipoprotein lipase (clearing factor), which is activated by testosterone (see, for instance, Breier et al. 1985). The intracellular hormone-sensitive lipase of adipose tissue catalyses the breakdown of stored triglycerides into glycerol and fatty acid with the latter ...

Renal excretion of free fatty acids
Clinica Chimica Acta, 1971Abstract Plasma and urine free fatty acids (FFA) were determined in the postabsorptive state in 25 subjects without renal disease. Urine contained 10.8 ± 2.7 μmoles/l FFA. The saturated fatty acids accounted for a higher percentage of the FFA in urine than in plasma. A correlation was observed between the urine/plasma ratios of FFA and creatinine and
