Carbohydrates are monosaccharides that are linked together via a ______ bond.

Explanation:
Carbohydrates are built from monosaccharides linked by glycosidic bonds. This bond forms when the hydroxyl group of one sugar’s anomeric carbon reacts with another sugar, typically in a dehydration synthesis that releases a molecule of water. The resulting glycosidic linkage can be in different orientations (alpha or beta), which influences the structure and digestibility of the resulting disaccharides and polysaccharides, such as starch (α-1,4) versus cellulose (β-1,4). This bond is distinct from other common bonds: peptide bonds join amino acids in proteins, phosphodiester bonds connect nucleotides in DNA/RNA, and ester bonds link fatty acids to glycerol in fats.
