Proteins are biological macromolecules composed of amino acids linked together by peptide bonds. A peptide bond is a covalent bond formed between the carboxyl group (–COOH) of one amino acid and the amino group (–NH₂) of another amino acid. This process occurs through a condensation reaction, also known as dehydration synthesis, in which a molecule of water (H₂O) is released.
