![]() ![]() Indicate the major types of apolipoprotein found in the different lipoprotein classes.Įxplain that triacylglycerol is carried from the intestine (after intake from the diet) to the liver in chylomicrons and from the liver to extrahepatic tissues in very low density lipoprotein (VLDL), and these particles are synthesized in intestinal and liver cells, respectively, by similar processes. Illustrate the structure of a lipoprotein particle. Identify the four major groups of plasma lipoproteins and the four major lipid classes they carry. These results highlighted the role of κ-CGN in alleviating diet-induced adiposity by promoting energy expenditure and suppressing the bioavailability of ingested lipids.After studying this chapter, you should be able to: Moreover, κ-CGN in high-fat diets inhibited lipid digestion and absorption, being associated with the decrease in lipid accumulation and improved serum lipid profile. The sirtuin1-mediated improvement of lipid metabolism was negatively associated with the levels of bile acids, especially for deoxycholic acid, 3β-cholic acid, glycodeoxycholic acid and glycolithocholic acid. Supplement of κ-CGN in high-fat diets significantly upregulated the genes and protein expression of Sirtuin1, which was accompanied by the increased gene expression of downstream fatty acids oxidation ( Cpt1a and Acadl). ![]() The κ-CGN supplement significantly suppressed the increase in body weight by 6.79 g on an average. The current study investigated the effect of κ-CGN in pork-based diets on the lipid metabolism of male C57BL/6J mice. ![]() However, its impact on the host metabolism is less revealed. Kappa-carrageenan (κ-CGN) is widely used in the meat industry. ![]()
