Neurotensin (1-11) retains the 11 amino acids on the basis of Neurotensin, and lacks two hydrophobic amino acids Ile-Leu on the original basis, so Neurotensin (1-11) has better hydrophilicity. From the perspective of peptide synthesis, the secondary structure of Neurotensin (1-11) has more extensibility and is prone to changes. Reasonable production technology and storage conditions can increase the stability of the peptide.
