An α-helix is a right-handed coil of amino-acid residues on a polypeptide chain, typically ranging between 4 and 40 residues. … WebActually, secondary structure is formed by hydrogen bonds of backbone only. No R-Groups are involved in secondary structure bonding. Proline definitely messes up both Beta sheets and Helices, but I am confident Glycine only messes up alpha helices due to its small size and the vertical (stacking) interactions. key vault secret attributes
