This long mixed-DL peptide contains a wide distribution of aromatic, polar, acidic, and basic residues that create highly diverse folding potential. Researchers examine its extended flexibility, β-turn formation, and intramolecular packing. The sequence supports mapping complex interaction networks and aggregation behavior. Its C-terminal amide enhances structural stability.
