Structural Composition
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
Physical Properties
The peptide’s 15-amino-acid configuration contributes to a distinct stability profile. Multiple proline residues within the sequence introduce conformational rigidity, which may enhance resistance to enzymatic degradation. The presence of both acidic residues (glutamic acid and aspartic acid) and a basic residue (lysine) results in a balanced charge distribution, supporting aqueous solubility.
