what process is used to link amino acids together

The process that links amino acids together is a dehydration (condensation) reaction that forms peptide bonds between them.

Quick Scoop

• Amino acids join when the carboxyl group (−COOH-COOH−COOH) of one reacts with the amino group (−NH2-NH₂−NH2​) of another.

• In this reaction, a molecule of water is removed, so it is called a dehydration or condensation reaction.

• The new covalent bond between them is called a peptide bond , a specific type of amide bond.

• Repeating this process many times links many amino acids into a polypeptide chain, which then folds into a functional protein.

In one sentence for exam-style use

Amino acids are linked together by dehydration (condensation) reactions that form peptide bonds between the carboxyl group of one amino acid and the amino group of the next.
