Formulation:White powder Molecular Formula:C29H53NO5 Molecular Weight:495.73 Specifications:40%~95% Purity: ≥99% by HPLC Description:Xenical is a drug designed to treat obesity. Its primary function is preventing the absorption of fats from the human diet, thereby reducing caloric intake. It is intended for use in conjunction with a physician-supervised reduced-calorie diet. Xenical is the saturated derivative of lipstatin — a potent natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini. Xenical works by inhibiting pancreatic lipase, an enzyme that breaks down triglycerides in the intestine. Without this enzyme, triglycerides from the diet are prevented from being hydrolyzed into absorbable free fatty acids and are excreted undigested.
