Cholesterol accelerates the binding of Alzheimer’s beta-amyloid peptide to ganglioside GM1 through a universal hydrogen-bond-dependent sterol tuning of glycolipid conformation.

Cholesterol accelerates the binding of Alzheimer’s beta-amyloid peptide to ganglioside GM1 through a universal hydrogen-bond-dependent sterol tuning of glycolipid conformation.

Age-related alterations of membrane lipids in brain cell membranes together with high blood cholesterol are considered as major risk factors for Alzheimer’s disease. Yet the molecular mechanisms by which these factors increase Alzheimer’s risk are mostly unknown. In lipid raft domains of the plasma...
