Carboxyl groups and amino groups form stable amide bonds, and can also form ester bonds with hydroxyl groups. Active esters react with primary amine groups at ph7-8.5 to form stable amide bonds. Polyethylene glycol increases drug solubility and stability, reduces the immunogenicity of peptides and proteins, and inhibits the nonspecific binding of charged molecules on the modified surface. It can modify proteins, peptides and other small molecular materials, and is widely used in pharmaceutical research, drug release, nano new materials research, and cell culture. It has become a research trend in the ligand research of active compounds, peptide synthesis carriers, polymer graft compounds, polyethylene glycol coating of new materials and modification functionalization.
