Dynamic structure of phospholipid bilayers on the path for oxygen diffusion in the ox lung.
The dynamic properties of the phospholipid bilayer of cell membranes were studied with a nanosecond fluorometer to obtain information on the microstructure of the path for oxygen diffusion in the ox lung. The viscosity in membranes of pneumocytes, endothelial cells from pulmonary artery, and erythrocytes was 47, 54 and 162 mPa . sec respectively. The wobbling angle representing the oscillation of phospholipid molecules was 47, 44 and 38 degrees, respectively.
