Rebaudioside M is a rebaudioside derived from rebaudioside A, where the hydroxy groups at positions 2 and 3 of the beta-D-glucosyl ester moiety are converted to beta-D-glucoside groups. Found in low concentrations in the leaves of Stevia rebaudiana, it is over 200 times sweeter than sucrose. It functions as a sweetening agent and is a beta-D-glucoside and rebaudioside. It is functionally related to rebaudioside A, rebaudioside D, and the structure beta-D-Glcp-(1->2)-[beta-D-Glcp-(1->3)]-beta-D-Glcp.
