Which of the following is false regarding alpha helix?
Alpha helix is stabilized primarily by intra chain hydrogen bonds. Alpha helix is the most common and stable secondary structure. A complete turn of the helix contains an average of 3.6 aminoacyl residues. Large numbers of charged amino acids(glutamte,aspaate,histidine,lysine,and arginine) disrupt the helix by forming ionic bonds or by electrostatically repelling each other.
