title: Influence of cholesterol on water penetration into bilayers.
abstract: X-ray diffraction and capacitance measurements have been used to calculate the depth to which water penetrates in fully hydrated bacterial phosphatidylethanolamine bilayers in the presence and absence of cholesterol. The data indicate that cholesterol decreases in depth of water penetration by about 2.5 angstroms.
