A double sugar formed from two monosaccharides in a dehydration reaction is called a

Explanation:
Joining two monosaccharides by a dehydration synthesis forms a disaccharide, a double sugar connected by a glycosidic bond with a molecule of water released in the process. This type of linkage creates a molecule with two sugar units, such as sucrose, lactose, or maltose. A monosaccharide is just one sugar unit, so it isn’t a double sugar. A polysaccharide contains many sugar units, not just two. A protein is a different type of macromolecule entirely, made from amino acids.
