Spin Probe Studies of Photo-Induced Structural Changes in Phospholipid Multibilayers Containing Light-Sensitive Pigments,
NATIONAL RESEARCH COUNCIL OF CANADA OTTAWA (ONTARIO) DIV OF BIOLOGICAL SCIENCES
Pagination or Media Count:
Biological photochemical processes, for example photosynthesis and vision, are closely associated with membranes. These processes are complex, both structurally and functionally, and many model system studies have been carried out in the attempt to understand the nature of the underlying elementary processes. Because lamellar structures are associated with chloroplasts and retinal rod segments, a number of photochemical properties of lipid bilayers containing chlorophyll and retinal have been carried out. The present communication indicates that illumination of phospholipid bilayers containing photoactive pigments can cause changes in the structural arrangement of the phospholipids, suggesting that such changes may play a role in biological photochemical processes.
