Abstract: | Improved X-ray diffraction data from dry nerve myelin are presented. In addition to the spacings of approx. 150 Å, 60 Å, 44 Å and 34.6 Å, which have been previously reported, we identify a 14 Å series. The data suggests that the hydrocarbon chains in the single bilayer () is ordered, whereas in the double bilayer () and in the fluid phase () it is disordered. It is shown that cholesterol () exists as a bilayer, and the 14 Å series is probably another cholesterol phase. |
