Opposing Roles of Cholesterol and Cholesterol Sulfate in Proton Transfer and Diffusion at Membrane Interfaces

This study shows cholesterol and cholesterol sulfate have opposing effects on proton transfer and diffusion at membrane interfaces, with cholesterol promoting local transfer and inhibiting long-range diffusion, while cholesterol sulfate does the opposite.

Proton migration on biological membranes: Lipid phase, temperature, and composition dependence of proton transfer processes and membrane proton barrier

This study investigates how membrane phase, temperature, and lipid composition affect proton transfer and diffusion on biological membranes.
