Poly-L-proline is a homopolymeric peptide composed of the amino acid proline, linked through peptide bonds in a linear sequence. Its ability to adopt distinct helical conformations makes it an ideal model system for studying the principles of protein folding and the structural preferences of polypeptides under various conditions. Furthermore, the PPII helix, in particular, is of great interest as it is often found in the extended regions of proteins that are involved in signaling and recognition processes.
