The peptide bond is known to be a chemical bond that is formed between two molecules. Usually, the carboxyl group will have a reaction with the amino group of another molecule.
This will help release the molecule of water available in the group. This is known to be a condensation reaction. Out of all the choices that are available, the peptide bond is C.
The formation of peptide bonds can be more evident through proteins. Peptide bonds are considered to be important because they are very helpful in the formation of protein. Peptide bonds are also known to be very strong and stable.
