What is the nature of the bond between monosaccharides in disaccharides?

The bond between monosaccharides in disaccharides is known as a glycosidic bond. This type of bond forms when a hydroxyl group of one monosaccharide reacts with the hydroxyl group of another monosaccharide, resulting in the release of a water molecule (a condensation reaction). The remaining oxygen atom connects the two monosaccharides, creating a glycosidic linkage.

This bond is critical in carbohydrate chemistry as it determines the structure and properties of the disaccharide formed. For instance, sucrose (table sugar) is made from glucose and fructose linked by a glycosidic bond, influencing its sweetness and digestibility.

Understanding glycosidic bonds is fundamental in biochemistry, as they are not only found in disaccharides but also in polysaccharides, which are crucial for energy storage and structural functions in living organisms.
