Secondary structure of a protein refers to the three-dimensional structure of local segments of a protein. Each type of secondary structure has segments that have a repeating conformational pattern which is produced by a repeating pattern of values for the [[Psi and Phi Angles|phi and psi torsional angles]]. For this reason on a [[Ramachandran Plots|Ramachandran plot]] | Secondary structure of a protein refers to the three-dimensional structure of local segments of a protein.

There are three common secondary structures - helices, β-pleated sheets and turns, and there are several variations of each one of them. | There are three common secondary structures - helices, β-pleated sheets and turns, and there are several variations of each one of them. | ||
