More about glucose

Molecular formula: C6H12O6

Molecular weight: 180.16

Glucose has water solubility of about 0.5 g per mL in water at room temperature.


Glucose has a clean sweet taste. It is about 70% as sweet as sucrose on a weight basis. The concentration vs. response relationship in water is shown below (results in food systems will vary). This graph is based on data from DuBois, Walters, Schiffman, Warwick, Booth, Pecore, Gibes, Carr & Brands in "Sweeteners: Discovery, Molecular Design, and Chemoreception," D.E. Walters et al., Eds., American Chemical Society, 1991. The graph allows you to estimate sweetness response (R) for any concentration (C). The units of R are percent sucrose equivalent; the units of C are percent glucose. The data points that lie close to the x-axis represent the amount of bitterness detected; for glucose, bitterness is essentially negligible at all concentrations.
