Common uses of D-fructose standard solution:

1. Calibration curve creation:
   By preparing a series of D-fructose standard solutions with varying concentrations, researchers can create a calibration curve to accurately determine the concentration of fructose in unknown samples using a spectrophotometer or other analytical instrument.
2. Enzyme assays: In experiments studying enzymes that metabolize fructose, a D-fructose standard solution is used to quantify the reaction rate.
3. Quality control:
   In food or beverage analysis, a D-fructose standard solution can be used to verify the accuracy of measurements.
