Secondary structure elements.

Common structural elements like α-helix, strand or β-sheet.

Proteins consist of a long chain of amino acids, the primary structure. This chain first folds into common secondary structure elements. These elements are known as α-helix and β-beta-sheets and are formed by hydrogen bonds between atoms in both the sidechains and backbone. The secondary structure elements are connected to each other by turns and random coils and loops.
