Glucose can be prepared from sucrose by boiling it with dilute HCl or H₂SO₄ in alcoholic solution. The products obtained are equal amounts of glucose and fructose through the hydrolysis of sucrose.

The preparation of glucose from sucrose involves the enzymatic hydrolysis of sucrose, commonly catalyzed by the enzyme invertase. This reaction breaks down sucrose into its constituent monosaccharides, glucose, and fructose. The process entails mixing sucrose with water and adding invertase, which facilitates the cleavage of the glycosidic bond in sucrose. The result is a mixture of glucose and fructose, commonly known as invert sugar. The reaction is represented as: C₁₂H₂₂O₁₁ + H₂O → C₆H₁₂O₆ + C₆H₁₂O₆. The obtained products, glucose and fructose, are both monosaccharides and can be used as sweeteners in various applications.
