Answer: Option D. forming water
Explanation: The combination or linking of amino acids results in the formation of chains called Peptides.
The reaction involved in the formation of peptides is called dehydration or condensation reaction. When two amino acids are linked together, the carboxyl group (COOH) of one of the amino acids and the amino group (NH2) of the second amino acid react together, water (H2O) is given off and a bond or chain is formed called the peptide bond( CO- NH).
