What are carbohydrates formed from two monosaccharides called?

Carbohydrates formed from two monosaccharides are known as disaccharides. This classification is based on the chemical structure and the bonding between the monosaccharide units. When two monosaccharides join together through a glycosidic bond, they form a disaccharide. Common examples of disaccharides include sucrose (table sugar), which is composed of glucose and fructose, and lactose, found in milk, which consists of glucose and galactose.

Monosaccharides are the simplest forms of carbohydrates and cannot be hydrolyzed into smaller carbohydrate units; hence, they do not apply in this context. Polysaccharides are larger carbohydrates, formed from many monosaccharide units, which also does not fit the definition that is being asked about. Complex carbohydrates is a broader term that often encompasses both oligosaccharides (which include disaccharides) and polysaccharides, but it is not specific to disaccharides alone.
