GRANDE, FRANCISCO, AND WILLIAM F. PRIGGE. Glucagon infusion, plasma FFA and triglycerides, blood sugar, and liver lipids in birds. Am. J. Physiol. 218(5) : 1406-1411. 1970.-Glucagon infusion produced elevations of plasma free fatty acids (FFA), triglycerides (TGL), and blood sugar in geeese and ducks. Free fatty acids rose promptly after the beginning of the infusion, reaching a level which was...

The present study aims at determining whether, and how, the molecular structure of fatty acids influences their mobilization from fat cells. The in vitro mobilization of 52 fatty acids ranging in chain length from 12 to 24 carbon atoms, in unsaturation from 0 to 6 double bonds, and including 23 pairs of positional isomers was examined. Fat cells were isolated from adipose tissue of rats fed a f...

The effects of spinal anaesthesia and surgery on carbohydrate and fat metabolism were studied in thirty patients by determining plasma concentrations of human growth hormone (HGH), insulin, blood glucose and free fatty acids (FFA). Hyperbaric spinal anaesthesia with lignocaine or quatacaiae alone and subsequent surgery did not influence the plasma HGH, insulin or FFA levels. Mean blood glucose ...

To counteract insulin resistance, it is necessary to increase the utilization rate of fatty acids in blood and adipose tissue. The aim of the present study was to determine the relation between metabolic responses and exercise duration from changes in the respiratory exchange ratio (RER). The mean RER during 30 minutes of moderate exercise (mean pulse 115 beats/min) was 0.89 +/- 0.02, indicatin...

BACKGROUND In vivo production of fatty acid-derived chemicals in Saccharomyces cerevisiae requires strategies to increase the intracellular supply of either acyl-CoA or free fatty acids (FFAs), since their cytosolic concentrations are quite low in a natural state for this organism. Deletion of the fatty acyl-CoA synthetase genes FAA1 and FAA4 is an effective and straightforward way to disable r...

Capparis decidua belongs to family Capparidaceae in wastelands of India. The study aim was determine the role C. fruits on free fatty acids (FFA) profile fat-rich diet (FRD) dyslipidemic rats. methanolic extract edible fruit (CD) given orally obese rats at dose 125 mg/kg and 250 for consecutive 28 days. CD treatment FRD significantly restricts body weight gains. Blood lipid altered dependently ...

MILLER, H. I., B. ISSEKUTZ, JR., P. PAUL, AND K. RODAHL. Effect of lad tic acid on plasma free fatty acids in pancreatectomized dogs. Am. J. Physiol. 207(6): 1226-1230. rg64.-Sodium lactate infusions into unanesthetized pancreatectomized dogs, with indwelling arterial and venous catheters, markedly decreased the plasma free fatty acid (FFA) level. Infusions of palmitate-rCl4 at constant rates s...

This study demonstrated that homogenization did not increase the activity of lipoprotein lipase (LPL) in spite of a fast accumulation of free fatty acids (FFA). Two homogenization pressures (100 and 170 bar) and two temperatures (40 ̊C and 50 ̊C) were examined. The activity of LPL was analyzed and the formation of FFA was measured with two different methods, the B.D.I.-method and a nonesterified ...

  This study was carried out to investigate the rate of lipid oxidation in fresh rainbow trout (Onchorhynchus mykiss) and in the sticks treated by (2.5% w/v) sodium acetate (NaA), sodium citrate (NaC) and sodium lactate (NaL). The pH value, free fatty acid (FFA), thiobarbituric acid (TBA) and sensory evaluation (odor, flavor and color) were determined on 0, 3, 6, 9 and 12 days of storage. The r...
