WebA radical (often, but unnecessarily called a free radical) is an atom or group of atoms that have one or more unpaired electrons. Radicals can have positive, negative or neutral charge. WebDec 20, 2024 · Reactive oxygen species (ROSs) represent the major agents of oxidative stress, which may be both beneficial and deleterious to the skin, and this group includes singlet oxygen ( 1 O 2 ), superoxide anion (O 2•− ), H 2 O 2, hydroxyl radical (•OH), and others. The gradual reduction of 1 O 2 leads to the production of O 2·−, H 2 O 2, and •OH [ 1 ].

WebReactive oxygen species play important roles in cell signalling, a process termed redox signaling. Thus, to maintain proper cellular homeostasis, a balance must be struck between reactive oxygen production and consumption. The best studied cellular antioxidants are the enzymes superoxide dismutase (SOD), catalase, and glutathione peroxidase.

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.
