검증된 단계별 안내1
Understand that a peptide bond is a covalent bond that links amino acids together in a protein chain.
Recognize that each amino acid has an amino group (\(\text{NH}_2\)) and a carboxyl group (\(\text{COOH}\)).
Identify that during peptide bond formation, the carboxyl group of one amino acid reacts with the amino group of another amino acid.
Note that this reaction results in the release of a water molecule (\(\text{H}_2\text{O}\)), a process known as a condensation reaction.
Conclude that the peptide bond is formed between the carbon atom of the carboxyl group of one amino acid and the nitrogen atom of the amino group of the next amino acid.
