Document Summary
Differ from phospholipids: different backbone, no po4, tend to have longer fa tails. Can more membrane microdomains that are less fluid and this matters because molecules diffusing in the membrane have a hard time diffusing out. Pathogens can gain entry to the cell because the efficiency of binding to their receptor is better. Viruses can also escape the cell from the other side of the lipid raft. Gangliosides - sphingolipids with sugar for an r group. Lipids know the subcategory of lipids. Diffuse at a rate of about 2 microns per second. Programmed cell death occurs in response to a signal. Clicker question: paula abdul"s necklace (pearls) looks most like . Liposome - because it has a double layer (2 layers) The graph below shows the relationship between membrane permeability and temperature of phospholipid bilayer containing saturated, monounsaturated or polyunsaturated fatty acid tails.
