H-Pro-Leu-Gly-Gly-OH is a flexible tetrapeptide in which proline imposes local constraints that influence chain conformation. Its glycine-rich tail supports studies of minimal folding behavior and turn-inducing motifs. Researchers employ it to analyze early structural determinants in peptide–protein interactions. The sequence aids modeling of flexible backbone systems.
