Which carbohydrate is formed through the condensation of two monosaccharides?

The formation of a disaccharide occurs through the condensation reaction of two monosaccharides. During this process, a water molecule is removed, and a glycosidic bond is formed, linking the two monosaccharides together. This defines disaccharides, which are sugars composed of two monosaccharide units. Common examples of disaccharides include sucrose (formed from glucose and fructose) and lactose (formed from glucose and galactose).

In contrast, glucose and fructose are considered monosaccharides, which are the simplest form of carbohydrates and cannot be further hydrolyzed into smaller carbohydrate units. Polysaccharides, on the other hand, consist of multiple monosaccharide units linked together, often resulting from the repeated condensation of monosaccharides, but they are not formed directly as a result of just two monosaccharides joining together.
