Disaccharides are formed from how many monosaccharide units?

Explanation:
Disaccharides are formed from two monosaccharide units. They come together through a glycosidic bond in a dehydration (condensation) reaction, which removes a water molecule. That’s why disaccharides like maltose, lactose, and sucrose contain two sugar units. If there were only one unit, it would be a monosaccharide; if there were three, it would be a trisaccharide; and if there were many, it would be a polysaccharide.
