What are the two monosaccharides that make up sucrose?

Sucrose is a disaccharide that consists of two monosaccharides: glucose and fructose. This combination results from a glycosidic bond formed through a condensation reaction between the two sugars. Glucose, a six-carbon monosaccharide, and fructose, a five-carbon monosaccharide, are both simple carbohydrates that provide energy. In contrast, the other options pair monosaccharides that do not constitute sucrose; for instance, galactose is part of lactose when combined with glucose, and maltose is made of two glucose units, while the pairing of glucose and fructose forms the foundation of sucrose specifically. Understanding this structure is essential for recognizing how different sugars interact and their roles in nutrition.
