Maltose is a disaccharide consisting of two glucose molecules, which can be broken down into two glucose monosaccharides through hydrolysis. During the hydrolysis process, water molecules participate in the reaction as catalysts, severing the chemical bonds between the maltose molecules and separating them into two glucose molecules. Therefore, the product of maltose hydrolysis is mainly glucose.

Glucose is a simple monosaccharide and is one of the most important sugars in the human body and other living organisms. It is one of the main sources of energy, which is produced by metabolism within cells. Glucose can also be used to synthesize other biomolecules such as fats, proteins and nucleic acids. Therefore, glucose, which is predominantly found in the hydrolyzed products of maltose, has important nutritional and metabolic functions.
