On the molecular mechanisms of the amyloid β-peptide aggregation
Proteins are tiny chemical machines that play many critical roles in our body. Some proteins send important messages, some carry crucial supplies, some fight with invaders and protect body from diseases, some clear trash etc. Proteins are strings of hundreds and thousands of small units called amino acids. If the string is built from less than hundred amino acids, it is called a peptide. DNA, a loThe pathogenesis of Alzheimer’s disease is widely believed to be due to production and deposition of the amyloid β-peptide. Several variants of the Aβ peptide are known to exist in in vivo. Variations include mutations or additional functional groups attached to residue side chains and may affect the aggregation process. Early on-set Alzheimer’s is caused by a variety of single amino acid substitu
