Abstract : Diabetes is a metabolic disorder characterized by the presence of elevated glucose in the blood and enhanced oxidative stress. It affects the cellular homeostasis that lead to the development of micro‐and macro‐vascular complications. Monocytes are the primary immune cells present in the circulatory system. Under high glucose conditions, the cells undergo oxidative stress and secrete reactive oxygen species. The enhanced release of reactive species are known to modify biomolecules like proteins and nucleic acids. Protein carbonylation, one of the most harmful and irreversible protein modifications, is considered as a key player in the progression of diabetes and associated complications. Hence, the present study explores the identification of carbonylated proteins from the monocytes under diabetic stress and determination of their site of modifications. Combined avidin affinity chromatography and bottom‐up proteomics experiments identified thirteen consistently expressed carbonylated proteins. Most of the identified proteins were reported to have altered functions under diabetic conditions that contribute to the development of diabetes associated inflammations and complications. We were able to determine oxidative stress‐induced modifications on Lys, Val, Ile, Cys, Thr and Asp residues.
