Given the melting point profile of a membrane bilayer consisting of the phospholipid below:

HC HC-O -R HC-o- -OCH,CH,NICH. R=palminate With Cholesterol (part d) 0.12- 0.1 0.12- 0.8 0.1 0.8 0.6 0.6 0.4 0.4 0.2 0.2 10 12 2 10 Temp C The x-axis is temperature in Cand the y-axis is degree of fluidity (higher value means the membrane is more does the curve shift if (sketch new curves on the graph on the above left and label a & b): a. Half the palminate were replaced with oleate b. The palminate was replaced with Stearate c Which Lipid bilayer would you rather have (a or b or the original) if you were an organism that needed to su cold environment?
