Soluble Aβ (Amyloid-beta, beta-amyloid, or Abeta) peptides, 36 to 43 amino acids in length, are natural proteolytic cleavage products of amyloid precursor protein (APP). However, soluble abnormally aggregated Aβ species are associated with Alzheimer's disease (AD), can be toxic to neurons, and insoluble Aβ aggregates are the main component of cerebral amyloid plaques, which are a pathological hallmark of AD.
