Web9 apr. 2024 · The inflammatory processes induced by oxidative stress can lead to mitochondrial and neurodegenerative diseases, diabetes, chronic diseases, and aging [ 34, 35 ]. In addition, it leads to the development of tumorigenesis and tumor angiogenesis processes, which are promoted by free radicals, especially ROS [ 36 ]. WebROS may damage various biomolecules, such as DNA, proteins, and lipids, and may contribute to the development of cancer, neurodegenerative diseases and other maladies. It also accelerates aging. Sulfur-containing amino acids including methionine are the major targets of ROS and thus the amino acids most susceptible to oxidation.
