Over 90% of protein oxidation occurs on specific amino acid residues, fundamentally altering protein structure and function. Understanding which amino acids can undergo oxidation is vital for investigating cellular damage, aging, and the mechanisms underlying various diseases. This process affects not only individual proteins but can also play a crucial role in overall cellular signaling and metabolic health.

Iron is an essential element for almost all living organisms, from bacteria to mammals, and the ferrous ion, Fe²⁺, is a key player in numerous fundamental processes. Its crucial biological role stems from its ability to readily donate and accept electrons, facilitating a wide array of biochemical reactions vital for life.
