Scavenging of superoxide by a membrane-bound superoxide oxidase [PDF]
Nature Chemical Biology, 2018 Superoxide is a reactive oxygen species produced during aerobic metabolism in mitochondria and prokaryotes. It causes damage to lipids, proteins and DNA and is implicated in cancer, cardiovascular disease, neurodegenerative disorders and aging. As protection, cells express soluble superoxide dismutases, disproportionating superoxide to oxygen and ...

Simulation studies of Cu(II) removal from aqueous solution using olive stone
Cleaner Materials, 2022 Heavy metal pollution is a growing environmental and health concern. Heavy metal ions, like Cu(II), undergo the Fenton reaction, producing hydroxide radicals and superoxides that cause DNA mutation (crosslinking and depurination) and carcinogenic damage ...

Superoxide Dismutases and Superoxide Reductases
Chemical Reviews, 2014 Superoxide, O2•–, is formed in all living organisms that come in contact with air, and, depending upon its biological context, it may act as a signaling agent, a toxic species, or a harmless intermediate that decomposes spontaneously. Its levels are limited in vivo by two different types of enzymes, superoxide reductase (SOR) and superoxide dismutase ...

Correlation-driven metal-insulator transition in unconventional magnetic metal superoxides
, 2023 Using first-principles electronic structure calculations, we have extensively studied the electronic and magnetic properties of alkali sodium superoxide (NaO2) in comparison with that of potassium superoxide (KO2) both at high and low temperatures. These
