Trafficking of dietary oleic, linolenic, and stearic acids in fasted or fed lean rats.
Increasing evidence supports the notion that there are significant differences in the health effects of diets enriched in saturated, as opposed to monounsaturated or polyunsaturated fat. However, the current understanding of how these types of fat differ in their handling by relevant tissues is incomplete. To examine the effects of fat type and nutritional status on the metabolic fate of dietar...
متن کاملOxidation of dietary stearic, oleic, and linoleic acids in growing pigs follows a biphasic pattern.
We used the pig as a model to assess the effects of dietary fat content and composition on nutrient oxidation and energy partitioning in positive energy balance. Pigs weighing 25 kg were assigned to either: 1) a low fat-high starch diet, or 2) a high saturated-fat diet, or 3) a high unsaturated-fat diet. In the high-fat treatments, 20% starch was iso-energetically replaced by 10.8% lard or 10.2...
متن کاملDuodenal infusions of palmitic, stearic or oleic acids differently affect mammary gland metabolism of fatty acids in lactating dairy cows.
The effect of dietary lipids on the fatty acid (FA) profile of cows' milk fat is mainly dependent on digestive processes and mammary gland uptake and metabolism of FA. The objective of this study was to determine the separate effects of high arterial concentrations of 16:0, 18:0 and cis-18:1(n-9) on uptake, synthesis and 18:0 desaturation rate in the mammary gland of lactating dairy cows, via a...
متن کاملThe distribution and biosynthesis of palmitic and stearic acids in liver, intestine, and carcass of intact normal and fasted rats.
Studies of biosynthesis of fatty acids in intact animals have been made usually by determining Cl4 activity in mixed fatty acids of liver or carcass after administration of radioactive acetate. Relatively few reports are available of such data obtained on individual fatty acids. Among the latter are included analyses of hepatic fatty acids (1, 2) and of carcass fatty acids (3, 4). In the experi...
متن کاملTurnover of liver ribosomes in fed and in fasted rats.
Evidence from many sources indicates that the ribonucleic acid and protein of normal animal tissues are replaced more rapidly than are the cells themselves. However, the significance of this macromolecular turnover and the mechanisms that regulate synthesis in concert with catabolism to maintain cellular composition have remained obscure. In beginning a study of factors that influence protein a...
