Peroxynitrous acid--where is the hydroxyl radical?

abstract：:Alzheimer's disease (AD) is characterized by the presence of senile plaques and neurofibrillary tangles in the brain. The beta-amyloid peptide (Abeta) is the primary constituent of the senile plaques, and has been proposed to be a key contributor to the neurodegeneration observed in AD. The molecular mechanisms underl...
