Reactive oxygen species free radical
WebJul 1, 2013 · The traditional view in the field of free radical biology is that free radicals and reactive oxygen species (ROS) are toxic, mostly owing to direct damage of sensitive and … ROS are produced by biochemical reactions that occur during the processes of respiration and photosynthesis in organelles such as mitochondria, peroxisomes and chloroplasts. During the respiration process the mitochondria convert energy for the cell into a usable form, adenosine triphosphate (ATP). The process of ATP production in the mitochondria, called oxidative phosphorylation, involv…

WebOxidative stress caused by reactive species of oxygen (ROS) damages cellular components and is recognized as one of the causes of chronic disease [19,20]. Human hepatoma cell line HepG2 is a reliable model for biochemical studies of intracellular antioxidant [ 21 ]. WebReactive oxygen species cause oxidative damage to several bacterial targets, including DNA (Imlay et al., 1988). As purine auxotrophs lack the ability to synthesize purine nucleotides and hence DNA and RNA, we hypothesized that the intramacrophage attenuation of purine auxotrophs might be due to their inability to repair DNA damage caused by ROS.

WebJan 1, 2024 · Reactive Oxygen Species (ROS) are small and highly reactive oxygen-containing molecules. ROS, when maintained at proper cellular concentrations, may function as “redox messengers” and play a significant role in intracellular signaling and regulation. WebApr 12, 2024 · The chemical reactivity of free radicals is directly associated with their potential to damage biological molecules. • OH is much more reactive than the other species and reacts rapidly with almost all chemical species, while H 2 O 2, NO • and O 2•− react quickly with a few molecules.
