This application discloses a process for reducing methionine sulfoxide residues in peptides and proteins to methionine residues. The process comprises subjecting said peptide or protein to a substantially anhydrous trifluoroacetic acid reaction medium containing from about 0.01M to about 3M of an organic sulfide and from about 0.01M to about 3M of a haloacid selected from the group consisting of hydrochloric acid, hydrobromic acid, and hydroiodic acid. |
