Answer: The correct answer is- Peptide bond.
A peptide bond is a chemical, covalent bond, which is formed between two molecules when -COOH ( carboxylic group) of one molecule reacts with -NH2 group ( that is amino group) of another molecule.
This bond formation releases a molecule of water ( H2O) thus, it is called a dehydration reaction.
This bond is usually formed between amino acids that are linked to each other in order to form polypeptide ( protein).
When α- COOH group of one amino acid links with the α- NH2 group of another amino acid, it will form a peptide bond.
