...re needed for physiological processes; others have antibacterial
properties. Amyloid peptides are chains of 40 to 42 amino acid residues. Due to their unique chemical architecture, consisting of water-loving and water-avoiding amino acid sequences, Alzheimer's peptides "self-assemble" to form tangles of fibrils i...
Scientists at Scripps Research Institute address mysteries of ozone in the human body
... The work of the TSRI scientists suggests that the antibacterial
effect of neutrophils is enhanced by antibodies. In addition to killing the bacteria themselves, the neutrophils feed singlet oxygen to the antibodies, which convert it into ozone, adding weapons to the assault. "This is really something new, and the...
