i le fuaitau o loo i lalo ona tali lea o le fesili mulimuli ane i le gagana lava lea e tasi e pei o le fuaitau: Fuaiupu: Amino acids eseese i lo latou tomai e fausia ai elemene eseese o le fausaga lona lua. Proline ma glycine ua lauiloa i nisi taimi o le "helical breaker" aua latou te faʻalavelaveina le masani o le α helical backbone conformation; ae ui i lea, e toʻalua uma e le masani ai agavaʻa faʻatulagaina ma e masani ona maua i taimi uma. Amino acids e fiafia e faʻaaoga faʻatulagaina helical i polotini aofia ai methionine, alanine, leucine, glutamate ma lysine ("MALEK" i amino-acid 1-letter codes); i se faʻafeagai, o le tele aromatic residues (tryptophan, tyrosine ma phenylalanine) ma Cβ-branched amino acids (isoleucine, valstronine, ma threonine) e fiafia e faʻaaoga β-andine. Peitai, o nei mea e fiafia i ai e
