WebPhosphatidylcholine is the most common phospholipid in cell membranes. Membranes behave as two-dimensional fluid. MOLECULES MOVE. The fluidity of a cell membrane- the ease with which its lipid molecules move within the plane of the bilayer- it is important for membrane function and has to be maintained within certain limits. WebSterols have a significant effect on membrane structure and properties of the lipid bilayer. They are typically shorter than the extended length of the neighboring phospholipids, but they act to increase membrane thickness, and maintain membrane fluidity at low temperatures, due to inter-lipid interactions. east lake public libraryWebAbstract. The Omega-3 fatty acid DHA (docosahexaenoic acid, 22:6) and its sister molecule EPA (eicosapentaenoic acid, 20:5) are highlighted here. These highly unsaturated fatty acids are widespread in nature, especially in the marine environment, and are essential in membranes ranging from deep sea bacteria to human neurons. east lake rec center
