Draw a sketch of a lipid bilayer, the structure that forms when a lipid such as phosphatidyl serine is dissolved in water.
The structure of a lipid bilayer is determined by the particular properties of its lipid molecules. What would happen if A. Phospholipids had only one hydrocarbon tail instead of two?B. The hydrocarbon tails were shorter than normal, say, about 10 carbon atoms long?C. All of the hydrocarbon tails were saturated?D. All of the hydrocarbon tails were unsaturated?E. The bilayer contained a mixture of two kinds of phospholipid molecules, one with two saturated hydrocarbon tails and the other with two unsaturated hydrocarbon tails?F. Each phospholipid molecule were covalently linked through the end carbon atom of one of its hydrocarbon tails to a phospholipid tail in the opposite monolayer?
Which of the following is incorrect regarding phospholipids?a. The heads are polar.b. The tails are nonpolar.c. They contain a phosphate group in place of one fatty acid.d. They are energy-storage molecules in the cell.
