What is the most common disaccharide formed from glucose and fructose?

The most common disaccharide formed from glucose and fructose is sucrose. This sugar is a product of a condensation reaction, where one molecule of glucose and one molecule of fructose are linked together through a glycosidic bond, releasing a molecule of water in the process. Sucrose is widely known as table sugar and is prevalent in many plants, particularly in sugar cane and sugar beets, which are major sources for commercial sucrose extraction.

Other options represent different disaccharides that do not form from the combination of glucose and fructose. For instance, lactose, found in milk, is composed of glucose and galactose, while maltose consists of two glucose molecules linked together. Galactose is a monosaccharide and not a disaccharide, thus it cannot be formed from the combination of glucose and fructose.
