The alpha helix (Î±-helix) is a common secondary structure of proteins and is a righthand-coiled or spiral conformation (helix) in which every backbone N-H group donates a hydrogen bond to the backbone C=O group of the amino acid four residues earlier (hydrogen bonding).ince the Î±-helix is defined by its hydrogen bonds and backbone conformation, the most detailed experimental evidence for Î±-helical structure comes from atomic-resolution X-ray crystallography such as the example shown at right.
