Plasma free fatty acid storage in subcutaneous and visceral adipose tissue in postabsorptive women.
OBJECTIVE We assessed the direct (VLDL-triglycerides [VLDL-TG] independent) storage of circulating free fatty acids (FFAs) in visceral and subcutaneous fat in postabsorptive women. RESEARCH DESIGN AND METHODS Twelve women (BMI 29.6 +/- 6.6 kg/m(2)) received an identical, intravenous bolus dose of [1-(14)C]oleate followed by timed subcutaneous fat biopsies (abdominal and femoral) and then omen...
متن کاملRelationship between leucocyte and plasma ascorbic acid concentrations.
Leucocyte and plasma ascorbic acid values were measured in healthy students, adult factory employees, and old people not receiving supplementary vitamin C and in healthy old people receiving 500 mg of vitamin C daily. Significant positive correlations between leucocyte and plasma ascorbic acid were found in all the groups. The regression lines differed significantly between one another within t...
متن کاملRelationship between plasma and muscle concentrations of ketone bodies and free fatty acids in fed, starved and alloxan-diabetic states.
1. Concentrations of ketone bodies, free fatty acids and chloride in fed, 24-120h-starved and alloxan-diabetic rats were determined in plasma and striated muscle. Plasma glucose concentrations were also measured in these groups of animals. 2. Intracellular metabolite concentrations were calculated by using chloride as an endogenous marker of extracellular space. 3. The mean intracellular ketone...
متن کاملEffects of free fatty acid elevation on postabsorptive endogenous glucose production and gluconeogenesis in humans.
Effects of free fatty acids (FFAs) on endogenous glucose production (EGP) and gluconeogenesis (GNG) were examined in healthy subjects (n = 6) during stepwise increased Intralipid/heparin infusion (plasma FFAs 0.8+/-0.1, 1.8+/-0.2, and 2.8+/-0.3 mmol/l) and during glycerol infusion (plasma FFAs approximately 0.5 mmol/l). Rates of EGP were determined with D-[6,6-2H2]glucose and contributions of G...
متن کاملIn vivo evidence of defective postprandial and postabsorptive free fatty acid metabolism in familial combined hyperlipidemia.
Overproduction of very low density lipoprotein (VLDL) is the major characteristic of subjects with familial combined hyperlipidemia (FCHL). As enhanced free fatty acid (FFA) flux to the liver may be one of the determinants of VLDL overproduction, we studied FFA changes and products of hepatic FFA metabolism in response to a 24-h oral fat loading test (50 g/m(2)) in 7 FCHL subjects and 7 matched...
