Work Step by Step
It is given that an amino acid forms a hydrogen bond with another amino acid 4 residues downstream of it. The bonding pattern is maintained for every fourth amino acid in the polypeptide chain and the pattern repeats itself over a significant part of the protein chain. Based on the given information, it can be concluded that the resulting structure is part of the secondary structure as it is involved in the local organization of the protein and it involves only hydrogen bonds.
