Carbohydrates

A molecule of sucrose (glucose + fructose), a disaccharide.

Carbohydrates are made from monomers called monosaccharides. Some of these monosaccharides include glucose  (C₆H₁₂O₆), fructose (C₆H₁₂O₆), and deoxyribose  (C₅H₁₀O₄). When two monosaccharides undergo dehydration synthesis, water is produced, as two hydrogen atoms and one oxygen atom are lost from the two monosaccharides' hydroxyl group.
