This chapter describes a mass spectrometry-based strategy that facilitates the unambiguous identification and characterization of proteins modified by lipid peroxidation-derived 2-alkenals. The approach employs a biotinylated hydroxyl amine derivative as an aldehyde/keto reactive probe in conjunction with selective enrichment and tandem mass spectrometric analysis. Methodological details are given for model...
Dysfunction of mitochondria has been linked to aging and the pathogenesis of many degenerative diseases. Aside from their primary function in energy production, mitochondria are considered as a major source and target of reactive oxygen and nitrogen species (ROS/RNS) in cells as well. The mitochondrial thiol proteome is a subset...
