Why are lipid rafts thicker than other parts of the bilayers?
A. Because the fatty acid chains attached to sphinolipids are longer ( 20 - 26 C-atoms) compared to other lipids (14 - 22 C-atoms).
B. Because the fatty acid chains attached to sphingolipids have fewer double bonds (0.1 - 0.4 double bonds) compared to other lipids (1.1 - 1.5 double bonds).
C. Because the fatty acid chains attached to sphingolipids have high affinity for cholesterol.
D. Both a & b offer the correct explanations.
E. Both b & c offer the correct explanations
