Abstract

Whether hydrated from vapor or immersed in liquid water, aligned multibilayers of dimyristoylphosphatidylcholine adsorbed to a single mica 'substrate' are shown by neutron diffraction to hydrate in all mesophases (e.g., L(β'), P(β'), and L(α)) 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.
