Maltose is a disaccharide formed from which two sugars?

1. Fructose and Galactose

2. Glucose and Fructose

3. Glucose and Glucose

4. Sucrose and Lactose

The correct answer is: Glucose and Glucose

Maltose is indeed a disaccharide that is formed specifically from two glucose molecules. This process occurs through a condensation reaction where two glucose units are linked together by a glycosidic bond, resulting in the formation of maltose. This disaccharide is commonly found in malted foods and beverages and plays a significant role in brewing and baking due to its fermentable sugar content. The other combinations provided do not produce maltose. Fructose and galactose do not link together to form maltose, nor do glucose and fructose. Sucrose, which consists of glucose and fructose, and lactose, which is made up of glucose and galactose, also do not produce maltose in their formation. Therefore, the only correct pairing that defines maltose is the combination of two glucose units.
