Promotion of food consumption by L-Glu, L-Ala and L-Asp. a Changes in food consumption by the addition of 5 mM amino acid to 400 mM sucrose by Canton-S flies (n = 20–26) (except tyrosine, for which we used its saturated concentration of ~2.7 mM). b–d Volume of 400 mM sucrose plus different concentrations of L-Glu (b), L-Ala (c), and L-Asp (d) consumed by Canton-S flies (n = 15–37). e Volume of 400 mM sucrose plus different concentrations of the other 17 amino acids combined consumed by Canton-S flies (n = 13–15). f Volume of 400 mM sucrose or 400 mM sucrose plus 5 mM L- or D-amino acid consumed by Canton-S flies (n = 20–26). Virgin females were used for all experiments shown in this figure. Data are shown as means ± SEM. NS, P > 0.05; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
