β-amyloid 12-28 is primarily used in scientific research to study the mechanisms and behavior of amyloid peptides, which are closely associated with Alzheimer's disease. Researchers utilize this peptide fragment to investigate the aggregation process of amyloid-beta, a key factor in the formation of plaques in the brain. By studying β-amyloid 12-28, scientists aim to better understand the structural and molecular interactions that contribute to the development of neurodegenerative diseases. This knowledge can aid in the design of therapeutic strategies and drugs targeting amyloid aggregation, potentially slowing or preventing disease progression. Additionally, it serves as a model compound for testing inhibitors that may disrupt amyloid formation, offering insights into potential treatments for Alzheimer's and related conditions.
