Weak interactions in ligand-receptor
pairs are important in biological systems.
However, the energetics of these interactions
are often difficult to quantify for ligandreceptor
pairs. Weak interactions are a part
of reorganization energy, which plays a role
in electron transfer reactions. Under certain
conditions the rate of electron transfer
Small, soluble, self-assembling peptide Aβ-oligomers, known as ADDLs
(amyloid-derived diffusible ligands), accumulate in the Alzheimer’s
disease (AD) brain as Aβ 12-mers and are thought to contribute to AD
neuropathological conditions. Unlike plaques, which were once thought
to cause neuronal death due to insoluble amyloid plaque deposits,
ADDLs initiate abnormal changes...
