Explanation

The secondary structure of a polypeptide refers to its regular folding patterns, such as alpha-helices and beta-pleated sheets, which are maintained by hydrogen bonding. This differs from the primary structure, which is the amino acid sequence, and the tertiary structure, which is the overall 3D shape.
