Question

Quizplus · Accepted Answer

Glycerophospholipids often contain unsaturated fatty acids, which have one or more double bonds causing kinks in their structure. These kinks reduce the attractive forces between the fatty acid chains, preventing them from packing closely together. This results in increased membrane fluidity, which is crucial for proper cell membrane function.
