Metabolite Identification
Common NameBetadex
DescriptionBetadex, also known as beta-cyclodextrin or cycloheptaamylose, belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Betadex is an extremely weak basic (essentially neutral) compound (based on its pKa). Betadex is an odorless tasting compound. Outside of the human body,.
