Summary of "Anti-obesity potential of rare sugar d-psicose by regulating lipid metabolism in rats."

d-Psicose is a new-generation sugar substitute with a low calorie count and can still offer the desirable sweetness. The objective of this study was to investigate the antiobesity potential of d-psicose and the possible mechanism using Wistar rats as the animal model. The animals were divided into five groups and supplemented with diets containing 5% of different carbohydrates, such as glucose, fructose, cellulose, d-psicose, and a control diet, for 4 weeks. After sacrifice, blood lipid profile, tissue morphology, and related genes participating in lipid metabolism were analyzed. The results indicated that the supplementation by d-psicose leads to minimum fat accumulation in rats when compared with the other carbohydrates. The blood lipid profile and antioxidative activity of the rat were also improved. d-Psicose can regulate lipid metabolism by increasing the lipid-metabolism-related enzymes such as SDH in serum and liver and HL in the liver. d-Psicose can prevent fat accumulation by suppressing the expression of lipogenesis-related gene ACCα and hepatic fatty acid uptake gene (FAS and SREBP-1c), while stimulating the expression for fatty-acid-oxidation-related gene including AMPK2α, HSL, and PPARα. In conclusion, d-psicose can be considered to be a healthy alternative to traditional sweeteners.

Medical and Biotech [MESH] Definitions

A family of vertebrate and insect lipid droplet associated proteins. They consist of a conserved N-terminal PAT domain (an alpha-helical region of about 110 amino acids), an 11-mer repeat region, and lipid-binding hydrophobic regions or 4-helix bundles near their C-termini. Perilipins transiently or constitutively localize to LIPID DROPLETS in ADIPOCYTES and FOAM CELLS, especially in regions adjacent to the PLASMA MEMBRANE and ENDOPLASMIC RECTICULUM. They are critical for lipid droplet synthesis and homeostasis as well as the regulation of lipid metabolism. Genetic variations in perilipins are associated with ATHEROSCLEROSIS; OBESITY; and DIABETES MELLITUS.

Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS. It can be caused by the presence of INSULIN ANTIBODIES or the abnormalities in insulin receptors (RECEPTOR, INSULIN) on target cell surfaces. It is often associated with OBESITY; DIABETIC KETOACIDOSIS; INFECTION; and certain rare conditions. (from Stedman, 25th ed)

Compounds that increase the enzymatic activity of LIPOPROTEIN LIPASE. Lipoprotein lipase activators have a potential role in the treatment of OBESITY by increasing LIPID METABOLISM. Note that substances that increase the synthesis of lipoprotein lipase are not included here.

Agents that increase energy expenditure and weight loss by neural and chemical regulation. Beta-adrenergic agents and serotoninergic drugs have been experimentally used in patients with non-insulin dependent diabetes mellitus (NIDDM) to treat obesity.

Substances that alter the metabolism of LIPIDS.
