Question

1. Describe why saturated fatty acids have higher melting points than do unsaturated fatty acids that have the same chain length. 2. What are the chemical components of a biological wax, and what is their general structure? 3. Show the basic structure of all glycerophospholipids. 4. Show the structure of sphingosine and indicate the relationship between sphingosine and ceramide. 5. What is the most significant chemical difference between triacylglycerols and glycerophospholipids that leads to their different functions? 6. In cells, fatty acids are stored as triacylglycerols for energy reserves. (a) What is the molecule to which fatty acids are esterified to form triacylglycerols? (b) Define the logic behind cells storing fatty acids in esterified form.
