• Resumen

  • Amyloid plaques are a sign of Alzheimer's disease, and bad news for humans. But these clusters of proteins could have driven the earliest life on Earth. They can behave as catalysts, a finding that lends weight to a theory that amyloids helped to trigger life-sustaining reactions before enzymes evolved. Without enzymes, metabolic reactions would not occur.
