An <scene name='77/778341/Ballstick/2'>alpha helix</scene> is a type of secondary structure, i.e. a description of how the main chain of a protein is arranged in space. It is a repetitive regular secondary structure (just like the beta strand), i.e. all residues have similar conformation and hydrogen bonding, and it can be of arbitrary length. | An <scene name='77/778341/Ballstick/2'>alpha helix</scene> is a type of secondary structure, i.e. a description of how the main chain of a protein is arranged in space.
