Related terms
- Sulfoxide
- The +15.995 Da methionine oxidation product. Elutes earlier than the parent on reverse phase. A handling finding, not a synthesis finding.
- Oxidation ladder
- The series of peaks from sequential oxidation of multiple oxidisable residues: parent, mono-sulfoxide, bis-sulfoxide. Diagnostic — a single early peak with no second rung is probably something else.
