The complex structural arrangement of some protein molecules, such as keratin, in which the single polypeptide chains of proteins spiral right-handedly to form helices. Each NH group is connected to a CO group by a hydrogen bond at a distance equivalent to 3 amino acid residues; the helix makes a complete turn for each 3. 6 residues. 2, record 1, English, - alpha%20helix

Structure hélicoïdale d'enroulement d'une chaîne peptidique, en fonction des contraintes imposées par les liaisons peptidiques et leurs dimensions spécifiques. Dans cette structure, existent environ 3,6 résidus d'aminoacides par tour de spire. Les chaînes latérales R des aminoacides se placent à l'extérieur de l'hélice formée par le squelette peptidique. Dans cette structure, l'unité périodique, un simple tour de spire de l'hélice, s'étend sur environ 0,54 mm le long de l'axe. La disposition des chaînes peptidiques sous forme d'hélice est favorisée par rapport aux autres structures hélicoïdales ou aux autres enroulements possibles, car elle permet l'établissement de liaisons par ponts hydrogène entre les spires successives de l'hélice. 2, record 1, French, - h%C3%A9lice
