Research progress of the structure of antiviral peptides

Antiviral peptides are a kind of small peptide molecules with biological activity which can destroy or inhibit virus particles.Owing to their unique molecular structure and mechanism of action,antiviral peptides have been widely studied,and in vitro or in vivo experiments have shown that some peptides have good antiviral effect.This review focuses on the structural charac-teristics of antiviral peptides.
