Some embodiments of the invention involve methods for introduction of various functional groups onto polypeptides, peptides and proteins by alkylation of thioether (a.k.a. sulfide) groups by ring opening reactions, creating new compositions of matter that may be useful for medical therapeutic or diagnostic applications. The thioether groups may either be present in the polypeptides, or may be added to polypeptides by chemical modification, such as by alkylation of thiol (sulfhydryl) groups.
