Explanation

A peptide bond is formed through a dehydration synthesis reaction between the carboxyl group of one amino acid and the amino group of another, releasing a molecule of water. This bond links amino acids together in proteins. Phosphodiester bonds connect nucleotides, glycosidic bonds link sugars, and hydrogen bonds are weaker interactions that stabilize structures.
