Fat metabolism is an important consideration in obesity. Alpha-linolenic acid-enriched diacylglycerol (ALA-DAG), which mainly occurs as ALA esterifies to 1,3-diacyl-sn-glycerol (1,3-DAG), has beneficial effects on fat metabolism and body weight compared with triacylglycerol (TAG). Moreover, compared
The present studies evaluated the effect of prazosin, a selective alpha 1-adrenergic antagonist, on some metabolic determinants of triacylglycerol-rich lipoproteins. Plasma triacylglycerols (TG), TG secretion rate, TG removal rate, plasma insulin, and glucose were evaluated postprandially in animals
Recent evidence suggests that fatty acids generated from intracellular triacylglycerol (TAG) hydrolysis may have important roles in intracellular signaling. This study was conducted to determine if fatty acids liberated from TAG hydrolysis regulate peroxisome proliferator-activated receptor alpha
BACKGROUND
In contrast to numerous methods for measuring alpha-amylase activity, the approved IFCC reference method offers an invariable time-independent constant product pattern, thus avoiding possibly changing stoichiometric calculations. However, reference methods do not lend themselves to
A comparison of six GROMOS parameter sets for aliphatic alkanes is presented using simulations of a triglyceride, trioctanoin, in the gel or alpha phase. It is found that the parameter set 43A2 results in a system that is rigid and close packed, forcing a collective tilt of the molecules, known
Controversial data on the antioxidant effects of tocopherols have already been shown in different test systems, yet delta-tocopherol was hardly considered. This study was designed to assess the effects and degradation of alpha-, gamma-, and delta-tocopherol in four concentrations from between 0.01
We present the adaptation of an IFCC method for alpha-amylase using 2-chloro-4-nitro-phenyl-alpha-D-maltotrio-side as substrate (1) suited for routine work at 37 degrees C. In the assay, a constant proportion of substrate, i. e. 92%, is directly converted to 2-chloro-4-nitrophenol and maltotriose.
The antioxidant effects of alpha- and gamma-tocopherols were evaluated in a model system based on the autooxidation of purified sunflower oil (p-SFO) triacylglycerols at 55 degrees C for 7 d. Both tocopherols were found to cause more than 90% reduction in peroxide value when present at
The purpose of this study was to evaluate the effects of prazosin, an alpha-1 adrenergic antagonist, on determinants of triacylglycerol metabolism in rats fed chronically diets high in starch or sucrose. Hepatic triacylglycerol secretion rate (HTGSR), lipoprotein lipase in white and brown adipose
The separation of gamma- and alpha-linolenic acid containing triacylglycerols with an identical acyl carbon number and degree of unsaturation was obtained on capillary supercritical fluid chromatography using a 25% cyanopropyl-75% methylpolysiloxane stationary phase. The resolution of
It is well known that the consumption of n-3 polyunsaturated fatty acid (PUFA) decreases the plasma triacylglycerol (TAG) level. The technology of elevating the content of n-3 PUFAs in pig meat has already reached a practical level. In this study, the effects of dietary lard containing higher
The effect of adrenaline on triacylglycerol synthesis and secretion was examined in isolated rat hepatocytes. Cells were incubated with 0.5 mM-[1-14C]oleate, and the accumulation of triacylglycerol and [14C]triacylglycerol was measured in the incubation medium. Triacylglycerol appearing in the
The within-subject and between-subject biological variation in the catalytic concentration of pancreatic alpha-amylase and triacylglycerol lipase in serum have been studied. The study was performed during a 13-month period in a group of 42 supposedly healthy individuals, 19 women and 23 men. All
The signal transduction pathways of intracellular calcium and adenosin 3',5'-cyclic monophosphate (cAMP) participate in the regulation of intrahepatic metabolism of very low density lipoproteins (VLDL). The adrenoceptors are linked to calcium and cAMP signal transduction pathways so it is proposed
Reported associations between Tumor Necrosis Factor-alpha (TNFA) and the postprandial triacylglycerol (TAG) response have been inconsistent, which could be due to variations in the TNFA gene, meal fat composition or participant's body weight. Hence, we investigated the association of TNFA
