what the hell is pegylation

Pegylation is a process in which polyethylene glycol (PEG) molecules are attached to a drug or therapeutic protein. PEG is a biocompatible polymer that can improve the properties of drugs, such as extending their half-life, reducing immunogenicity, and enhancing their stability. Pegylation involves covalently attaching PEG chains to the drug molecule, typically through chemical reactions. This modification can alter the drug's pharmacokinetics, making it more effective for therapeutic purposes.
