||"in vitro spherical
thin lipid membranes were made from the total lipid extracts, as well as
from each of the major lipid constituents - phosphatidyl choline, phosphatidyl
ethanolamine, sphingomyelin, and cholesterol-of human red cell membranes.
All of these membrane preparations underwent a thinning process
lasting about 10 to 20 min as revealed by interference colors typical of
white light reflected from a thin film, followed by a rapid blackening in
spots at first and then ultimately of the entire free surface. The preparations
withstood gentle stirring and were stable for 1 to 2 hr."
||"The permeability constants to D-glucose of various lipid membranes
are summarized in the Table. It is interesting to note that the observed
permeability to D-glucose of the membrane made from the protein-free
total lipids of the ghosts in the present study, 2.3x10^-10 cm/sec, is some 100-fold lower than that of the membrane made from the crude total
lipids of the ghosts (Jung & Snell, 1968)."
