3. For the multilayer sample oriented with respect to the X-ray or neutron beam as given in Fig. 3, lamellar meridional data can be recorded along the z* axis and equatorial data along the x* axis. For many of the membrane systems employed in these studies, the signal to noise for lamellar meridional diffraction is much greater than that for equatorial diffraction and such studies to date have focused on the analysis of the former. 32 L E O G.

This study was extended to the native form of the membrane using biosynthetically deu terated phospholipids and phospholipid exchange proteins. Again, the major findings from this study (Blasie et ai, 1984; Herbette et ai, 1984b, 1985d) were (1) the asymmetry in protein mass distribution between the two monolayers of the sarcoplasmic reticulum membrane bilayer; (2) the greater number of phospholipids in the inner vs the outer monolayer of the membrane bilayer, and (3) structural features of the protein knob external to the membrane bilayer as schematically depicted in Fig.
VII. Conclusions X-Ray and neutron diffraction can be powerful tools for defining the precise interaction of small molecules with model and biological mem branes. When combined with other methodologies, these tools can pro vide valuable information for defining the molecular mechanism of this interaction.
