Which term describes a double sugar molecule made of two monosaccharides bonded through dehydration synthesis?

• A. Compound
• B. Disaccharide
• C. Carbohydrate
• D. Element

Answer: (B)

When two monosaccharide units join through dehydration synthesis, a water molecule is released and a glycosidic bond forms between them, creating a disaccharide. This specific term describes a double sugar made from two simple sugars, and examples include sucrose, lactose, and maltose. By contrast, a carbohydrate is a broad category that includes sugars of all sizes, not just double sugars. An element is a pure substance made of one type of atom, and a compound is a general term for a substance composed of two or more elements.
