H-Gly-Pro-Gly-Gly-OH is a characteristic tetrapeptide composed of a glycine-proline-glycine-glycine sequence[1]. H-Gly-Pro-Gly-Gly-OH can be used as an important molecular building block in research for the synthesis of more complex polypeptides. H-Gly-Pro-Gly-Gly-OH also provides a concise model sequence for investigating protein-protein interactions, particularly those involved in cell adhesion and signal transduction[2].
