Which disaccharide is created from glucose and fructose?

The disaccharide formed from the combination of glucose and fructose is known as sucrose. This sugar is commonly referred to as table sugar and is found in many plants. The formation of sucrose occurs through a glycosidic bond that links the anomeric carbon of glucose (in its alpha or beta form) to the anomeric carbon of fructose. The process involves a dehydration reaction, during which a molecule of water is released.

Understanding the structure of sucrose helps clarify its role in nutrition and metabolism. Sucrose is readily broken down in the body into its constituent monosaccharides, glucose and fructose, upon consumption, which are then utilized as quick sources of energy.

Lactose is composed of glucose and galactose, while maltose consists of two glucose molecules. Galactose, on the other hand, is a monosaccharide in its own right and is not formed from a combination of glucose and fructose. Thus, sucrose stands out as the correct answer due to its specific formation from glucose and fructose.
