Alpha Helix: Alpha Helix is a right-handed coiled rod-like structure. Beta Pleated Sheet: Beta sheet is a sheet-like structure. Formation. Alpha Helix: Hydrogen bonds form within the polypeptide chain in order to create a helical structure.

Figure 8.5 describes two major fundamental structural motifs of protein structure: the α helix and the β sheet. In addition to these well-defined structures, regions of a polypeptide can exist in an unordered configuration. The most common types of secondary structures are the α helix and the β pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another. Image credit: OpenStax Biology. The α-helix is not the only helical structure in proteins. Other helical structures include the 3_10 helix, which is stabilized by hydrogen bonds of the type (i, i+3) and the π-helix, which is stabilized by hydrogen bonds of the type (i, i+5).

Beta pleated sheets are made of beta strands connected laterally by two or more hydrogen bonds forming a backbone.
