  14. 14. Case Studies Cell Penetrating PeptidesAttached to a CPP, therapeutic cargo is delivered to an intracellular target,thus overcoming the entry restrictions set by the plasma membrane. 14
  15. 15. Case Studies N-Terminal Acetylation and C-Terminal Amidation Both modifications are free of chargeChemically synthesized peptides have free amino and carboxyl termini.N-terminal acetylation and C-terminal amidation reduce the overall charge of the peptide. This can 15increase the stability of the peptide and its resemblance to the native protein.
