A researcher is analyzing the primary structure of a newly isolated peptide hormone. The peptide consists of a sequence of amino acids linked by bonds formed through a dehydration reaction.
What is the nature of this peptide bond?
- It is an ester bond that is easily hydrolyzed by simple changes in pH.
- It is an amide bond that exhibits partial double-bond character.
- It is a disulfide bridge formed between cysteine residues.
- It is a non-covalent hydrogen bond that stabilizes the alpha-helix.
