Which of the following describes double sugars made when two monosaccharides are linked together?

Double sugars formed from the linkage of two monosaccharides are specifically known as disaccharides. When two monosaccharides undergo a condensation reaction or dehydration synthesis, they form a covalent bond, resulting in a disaccharide. This process involves the removal of a water molecule and the establishment of a glycosidic bond between the two sugar molecules.

Monosaccharides, on the other hand, are the simplest form of carbohydrates and cannot be further hydrolyzed into smaller sugars, which is why they do not apply to this question. Polysaccharides consist of long chains of monosaccharide units bonded together and are therefore more complex than disaccharides. Carbohydrates is a broader term that encompasses monosaccharides, disaccharides, and polysaccharides but does not specifically refer to the double sugars formed by the combination of two monosaccharides. Hence, the correct term for that specific linkage is disaccharides.
