Mitochondria are a significant source of reactive oxygen species (ROS) in mammalian cells (2, 11), which contributes to redox signaling under physiological and patho-logical conditions (5). It has been shown that hyperoxia-induced ROS formation in lung capillary endothelial … WebGlutathionyl-haemoglobin (Hb-SSG) is a minor form of haemoglobin characterized by the presence of a disulfide bond between the β-93 cysteine residue and the thiol group of glutathione. Hb-SSG is naturally present in the erythrocytes at levels comparable to those of glycated haemoglobin and can be measured by MALDI mass spectrometry on very small …
