Cell membrane fluidity refers to the dynamic nature of the lipid bilayer that makes up the cell membrane, allowing lipids and proteins to move laterally within the layer. This fluidity is crucial for many cellular processes, including membrane protein function, vesicle formation, cell signaling, and endocytosis. The fluidity of the membrane depends on several factors: the composition of lipids, the degree of saturation of fatty acid chains, the presence of cholesterol, and temperature. Unsaturated fatty acids introduce kinks in the hydrocarbon chains, preventing
