Fig. 5. Time course for the changes in plasma D-glucose (left panel) and insulin (right panel) concentrations after oral administration of D-fructose (6.9 µmol/g; closed circles and dashed line) or sucrose (3.7 µmol/g; crosses and solid line). Control experiments are shown as open circles and solid line. Mean values (± SEM) refer to 3 (control experiments) or 4 (D-fructose or sucrose administration) individual measurements.
