Still, both are highly reactive to attacks on their market share, and could be spurred to earlier development if they perceive a competitive threat from Canada.
Although O2 is not reactive enough to attack macromolecules directly, it can start an ROS chain formation.
Additionally, the NADPH oxidase complex generates reactive oxidative species to attack internalized microorganisms (for review see Romani, 2004; Segal, 2005).
Recently, another class of cellulases has come to light that employ reactive oxygen species to attack glycosidic bonds in cellulose [ 21, 22].
The superoxide radicals can rapidly react with nitric oxide to produce the more toxic peroxynitrite anion (ONOO-), or the highly reactive hydroxyl radical (OH ., to attack proteins, DNA, and membrane lipids.
Like 3 out of 10 kidney-transplant candidates, she had tested positive on a blood test called P.R.A., for panel-reactive antibody — proteins primed to attack foreign tissue, including her mother's.
Reviewed elsewhere [49], telomeric DNA appears to be especially susceptible to attack by reactive oxygen species.
The reactive species are produced primarily to attack invading microorganisms by nitration, oxidation, and chlorination reactions.
Biological membranes have high levels of polyunsaturated acids that make them susceptible to attack by reactive oxygen species (ROS) [ 89, 90].
Mucins are susceptible to attack by reactive oxygen species during which terminal sugars are lost and both protein and sugar moieties are fragmented [ 9].
