Scanning tunneling microscopy has been used to demonstrate that a spiral structure based on -reverse turns is adopted by the repeat sequences present in a group of wheat gluten proteins. This structure is smilar to the «spiral formed by a synthetic polypentapeptide based on a repeat sequence present in elastin. Wheat gluten and elastin are both elastomeric and it is possible that the spiral structure contributes to this property.
