Verified step by step guidance

Understand the context: Peptide bond formation occurs during protein synthesis, where amino acids are linked together to form polypeptides.

Identify the functional groups involved: The carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid participate in the reaction.

Describe the reaction mechanism: A condensation reaction occurs, where a molecule of water (H2O) is removed as the carboxyl group and amino group combine.

Explain the bond formed: The resulting bond is a covalent bond known as a peptide bond (or amide bond), which links the carbon atom of the carboxyl group to the nitrogen atom of the amino group.

Clarify the significance: Peptide bonds are essential for forming the primary structure of proteins, enabling amino acids to be joined in a specific sequence.
