Membrane Fluidity: Length of carbon tails and saturation levels Membrane fluidity depends on the length of the carbon tails in the phospholipid molecules and the presence or absence of double bonds. In the interactive, use the drag bars to change the lengths of the carbon talls in the phospholipids and toggle on and off the presence of double bonds (saturation vs. unsaturation). Then assess the transition temperatures (Tm) of membranes composed of the following phospholipid molecules and select the two that have the most similar transition temperatures.
Check All That Apply
O A phospholipid with 14 carbons and double bonds
O A phospholipid with 14 carbons and 1 double bond
O A phospholipid with 20 carbons and O double bonds
O A phospholipid with 24 carbons and 1 double bond
