Which disaccharide is made from glucose and fructose?

Sucrose is the disaccharide formed from the combination of glucose and fructose. This sugar is commonly known as table sugar and is found naturally in many plants, especially sugar cane and sugar beets.

The formation of sucrose occurs through a glycosidic bond between the glucose and fructose molecules during a dehydration synthesis reaction. This process involves the removal of a water molecule, allowing the two monosaccharides to join together.

In contrast, maltose is composed of two glucose units; lactose consists of glucose and galactose; and galactose is actually a monosaccharide, not a disaccharide. Understanding the specific combinations of monosaccharides that create various disaccharides is crucial for recognizing the different sugars present in foods and their impact on nutrition.
