Rebaudioside D (Standard) 

Rebaudioside D (Standard) is the analytical standard of Rebaudioside D. This product is intended for research and analytical applications. Rebaudioside D is an orally active sweetener that targets and activates FXR, modulates Acetyl-CoA Carboxylase, and inhibits 3-hydroxy-3-methylglutaryl-CoA reductase. Rebaudioside D regulates bile acid homeostasis and lipid metabolism, reduces the synthesis rates of fatty acids and cholesterol, and exerts multiple effects including anti-adipogenesis, hepatoprotection, anti-steatosis, gut microbiota modulation, enhancement of secondary bile acid metabolism, anti-endotoxin activity, regulation of bile acid transport, and inhibition of bile acid efflux. Rebaudioside D also reduces body weight gain, visceral fat accumulation, hepatic triglyceride and cholesterol accumulation, hepatic lipid peroxidation, and decreases the circulating level of lipopolysaccharide-binding protein. Rebaudioside D additionally enhances the secondary bile acid metabolic pathway of intestinal bacteria, upregulates the gene expression of ileal organic solute transporter α, and downregulates the gene expression of hepatic bile salt export pump. Rebaudioside D does not affect glucose homeostasis, alter total caloric intake or fecal energy excretion, induce weight gain, exacerbate obesity, promote hepatic steatosis, impair brown adipose tissue function, nor change skeletal muscle metabolism-related proteins. Rebaudioside D can be used in diet-induced obesity and obesity-related research.
