Difference Between Alpha and Beta Helix WebThere are two main types of secondary structures. Two fibrous structures the alpha helix, and the beta pleated sheet, which are structural components of the cell. The alpha helix is formed when the polypeptide chains twist into a spiral. This allows all amino acids in the chain to form hydrogen bonds with each other.
