Which of the following disaccharides is composed of glucose and fructose?

The disaccharide composed of glucose and fructose is sucrose. Sucrose is commonly known as table sugar and is found naturally in many plants. It serves as a primary carbohydrate source in the human diet and plays a significant role in providing energy.

Maltose, on the other hand, is made up of two glucose molecules and is commonly found in malted foods and beverages. Lactose consists of glucose and galactose and is the sugar found in milk. Galactose is actually a monosaccharide rather than a disaccharide, as it cannot be further hydrolyzed into simpler sugars.

Understanding the composition of these disaccharides highlights the differences between them, particularly in their sugar combinations and their roles in nutrition.
