Abstract
Whether hydrated from vapor or immersed in liquid water, aligned multi bilayers of dimyristoylphosphatidylcholine adsorbed to a single mica ' 'substrate'' are shown by neutron diffraction to hydrate in all mesoph ases (e.g., L-beta', P-beta', and L alpha) to the same extent as their liposomal counterparts suspended in liquid water. These data clearly demonstrate that the commonly accepted vapor pressure paradox does not exist.
