Question

What kind of reaction forms a peptide bond

Answer 1

a peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the the other molecule releasing a molecule of water (H2O)
It's a dehydration synthesis reaction (AKA Condensation reaction) and usually occurs between amino acids

Answer 2

Dehydration synthesis reaction forms a peptide bond.

A peptide bond is formed when the carboxyl group of one molecule reacts with the amino group of another molecule, producing a molecule of water (H2O). This reaction is a dehydration synthesis reaction (also called a condensation reaction) and it often takes place between amino acids.
