Bar Plot from Scientific Research

Activation of BmGr9 by a panel of sweet compounds, measured as the change in fluorescence relative to that for d -fructose. Bars are mean ± s.e.m. with independent samples ( n = 4) shown as open circles. Insets show Fischer projections of the epimers d -fructose and l -sorbose, with carbons numbered and difference highlighted in blue.
