Follicle cells in your scalp assemble proteins to build new hair. This most likely involves __________ reactions.
Zarrin [17]

Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule. Amino acids connected via peptide bonds form a polypeptide chain, which then chemically interact with other polypeptides in order to create a complex three-dimensional structure of the protein.
