Most proteins consist of linear [[polymer]]s built from series of up to 20 different [[Chirality (chemistry)#In biochemistry|<small>L</small>-α-]] amino acids. All [[proteinogenic amino acid]]s possess common structural features, including an [[alpha carbon|α-carbon]] to which an [[amino]] group, a [[carboxyl]] group, and a variable [[side chain]] are [[chemical bond|bonded]]. Only [[proline]] differs from this basic structure as it contains an unusual ring to the N-end amine group, which forces the CO–NH amide moiety into a fixed conformation. The side chains of the standard amino acids, detailed in the [[list of standard amino acids]], have a great variety of chemical structures and properties; it is the combined effect of all of the amino acid side chains in a protein that ultimately determines its three-dimensional structure and its chemical reactivity.
The amino acids in a polypeptide chain are linked by [[peptide bond]]s. Once linked in the protein chain, an individual amino acid is called a ''residue,'' and the linked series of carbon, nitrogen, and oxygen atoms are known as the ''main chain'' or ''protein backbone.''
