Rebaudioside A (sometimes shortened to "Reb A") is a steviol glycoside that is 200 times sweeter than sugar.[2] The glycoside contains only glucose (to the exclusion of other commonly found monosaccharides) as its monosaccharide moieties. It contains four glucose molecules in total with the central glucose of the triplet connected to the main steviol structure at its hydroxyl group, and the remaining glucose at its carboxyl group forming an ester bond.
