This type of representation of a protein structure is called “sticks representation”. To get a better impression of how a helix looks like, only the main chain of the polypeptide is shown, no side chains. There are 3.6 residues/turn in an α-helix, which means that there is one residue every 100 degrees of rotation (360/3.6).

Charged single alpha-helix: a versatile protein structural motif. Proteins. 2009 Mar;74(4):905-16. doi: 10.1002/prot. α‐Helices were extracted from the Protein Data Bank (PDB) and were divided into groups according to their sizes.
The discovery of the alpha helix was early in Dr. Branson’s career, and he would spend most of his time researching and teaching at Howard University. In his tenure, he published numerous papers on the molecular properties of Sickle cell disease 3 —a group of conditions in which the superstructure of the hemoglobin protein is distorted in a way that causes red blood cells to be shaped like An Amphipathic Helix In the protein in which this helix is found, it lies across the surface with one side of the helix facing the protein and the other side facing the aqueous medium. In this view, hydrophobic amino acids along this sequence have been colored green while polar and charged amino An alpha helix, sometimes called a Pauling-Corey-Branson alpha helix, is a coil of amino acid chain. It almost always coils in the right-handed direction. In an alpha helix, every partially-positive amino group sticks to the partially-negative oxygen in the carboxyl group of the amino acid four residues earlier on the chain.

Linus Pauling - Wikipedia α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure. The secondary structure of α-keratin is very similar to that of a traditional protein α-helix and forms a coiled coil.

Pauling first described the alpha-helix nearly 50 years ago, yet new features of its structure continue to be discovered, using peptide model systems, site-directed mutagenesis, advances in theory, the expansion of the Protein Data Bank and new experimental techniques. As you follow the helix around through 36 a-amino acidunits you make 10 complete 360¡turns and travel 5.4 nm in the forward direction (1 nm = 1x10-9m).
