Periodate oxidation of methionine in proteins
Analytical Biochemistry, 1982Abstract Treatment of free methionine with an equimolar amount of periodate gave nearly quantitative formation of the sulfoxide; treatment of free methionine sulfoxide with equimolar periodate gave nearly equal amounts of the original sulfoxide and the sulfone.

Performic Acid Oxidation of Proteins
Cold Spring Harbor Protocols, 2007INTRODUCTIONDisulfide bond cleavage is a prerequisite to many peptide-mapping strategies. It facilitates protein unfolding and thus optimizes proteolytic digestion. It also simplifies the interpretation of peptide maps by removing possible peptide fragment(s) in the mixture that are held together by disulfide bonds.

Oxidation of Proteins in Neonatal Lungs
Pediatrics, 1994Objective. To develop a method capable of quantifying the oxidative modification of proteins in pulmonary fluid obtained during routine suctioning of neonates receiving ventilation, thus providing an integrated assessment of antioxidant defenses. Design. Consecutive sample of neonates receiving ventilation.

Oxidative modifications of protein structures
2001Publisher Summary This chapter discusses the oxidative modifications and biological effects of protein structures. Proteins undergo oxidative modifications due to the complexity of their chemical structures in subsequent stages which depend on the presence of oxidation, susceptible groups and on steric availability of these groups for oxidant attacks.

Protein glutathionylation and oxidative stress
Journal of Chromatography B, 2007Liquid chromatography/electrospray ionization-mass spectrometry (LC/ESI-MS) demonstrated that glutathionyl hemoglobin (Hb) levels are increased in patients with diabetes, hyperlipidemia, uremia and Friedreich's ataxia. Glutathionylation of Hb is enhanced by oxidative stress.
