You are studying the properties of an Antarctic fish and a tropical fish. What differences might you observe in the composition and/or structure of their lipids? Explain. **Hint: membranes should be flexible a balance between providing structure but also remaining fluid. For these applications, consider what type of lipids (length, number of double bonds) are needed to maintain that balance. You will not have to name the lipids, but describe their shape and structure. Also keep in mind that the hydrophobic interactions between the fatty acids themselves are the most crucial factors to fluidity and that backbones (glycerol vs. sphingosine) and head groups (e.g. phosphates, sugars, cholines, etc.) will not significantly alter fluidity.
