{{Protein structure}}
'''Protein primary structure''' is the [[Biomolecular structure#Primary structure|linear sequence]] of [[amino acid]]s in a [[peptide]] or [[protein]].<ref name="sanger">{{Cite book |author=SANGER F |chapter=The arrangement of amino acids in proteins |volume=7 |pages=1–67 |year=1952 |pmid=14933251 |doi=10.1016/S0065-3233(08)60017-0 |editor=M.L.

[[Protein biosynthesis]] is most commonly performed by [[ribosome]]s in cells. Peptides can also be [[Peptide synthesis|synthesized]] in the laboratory. Protein primary structures can be [[Peptide sequencing|directly sequenced]], or inferred from [[DNA sequences]].
