Case Studies
Chemically synthesized peptides have free amino and carboxyl termini.
N-terminal acetylation and C-terminal amidation reduce the overall charge of the peptide. This canincrease the stability of the peptide and its resemblance to the native protein.
N-Terminal Acetylation and C-Terminal AmidationBoth modifications are free of charge
