Question

Quizplus · Accepted Answer

All of these factors directly or indirectly contribute to the transition temperature of a lipid bilayer. The ability of lipid molecules to be packed together affects the overall structure and stability of the bilayer. Saturated fatty acid chains tend to pack together more tightly, increasing the transition temperature, while unsaturated fatty acid chains with double bonds can introduce kinks in the chains, reducing the packing and lowering the transition temperature. The extent of unsaturation also plays a role, with more unsaturated fatty acids resulting in lower transition temperatures. Finally, the length of the fatty acid chains can influence the packing and flexibility of the bilayer, affecting the transition temperature.
