According to basic research, steviol glycosides and steviol interact with a protein channel called TRPM5, potentiating the signal from the sweet or bitter receptors, amplifying the taste of other sweet, bitter and umami tastants. The synergetic effect of the glycosides on the sweet receptor and TRPM5 explains the sweetness sensation. Some steviol glycosides (rebaudioside A) are perceived sweeter than others (stevioside).
