Protein | Secondary structures | Percentage composition

The two most common secondary structures within a protein are alpha helixes, and beta-sheets. However, remember that there are multiple types of alpha helixes and beta-sheets, and all have slightly different properties. Overall, alpha helixes and beta sheets are in approximately equal amounts. Anything not regarded as an alpha helix or a beta sheet is typically referred to as a “irregular structure“. This can include random coil, coil structures, Beta-hairpin turns, in addition to a seemingly infinite number of unnamed structures. Overall, there is as much irregular structure as beta sheet and alpha helix within a protein, and the correct answer is 33% for all three.
