Maamino acids anofarira kutora helical conformations mumapuroteni anosanganisira methionine, alanine, leucine, glutamate uye lysine ("MALEK" mune amino-acid 1-letter codes); Mukupesana, makuru anonhuwirira masara (tryptophan, tyrosine uye phenylalanine) uye Cβ-branched amino acids (isoleucine, valine, uye threonstrine) anofarira kutora β-andine conformations. Zvisinei, izvi zvishuwo hazvina kusimba zvakakwana kuti zvigadzire nzira yakavimbika yekufungidzira kutevedzana kubva kune yechipiri chimiro.
