question.
The a Helix • Helical backbone is held together by hydrogen bonds between the backbone amides of an n and n+4 amino acids The hydrogen bonds are aligned roughly parallel with the helical axis • Side chains point out and are roughly perpendicular with the helical axis Right-handed helix with 3.6 residues (5.4 Å) per turn (5.4 Å is the linear distance) Question: What is the length of a polypeptide consisting of 100 aa if the entire peptide is in a single a-helical conformation? .
