Membrane lipid composition

Membrane lipids are molecules that form the structure of cell membranes, creating a flexible barrier. They mainly consist of phospholipids, which have two fatty acid tails and a phosphate head, and cholesterol, which adds stability. This composition allows membranes to be fluid and adaptable, enabling functions like nutrient transport and signaling. The specific types and amounts of lipids vary between cells and environments, influencing membrane properties such as fluidity, permeability, and interactions with proteins. Overall, membrane lipid composition is essential for maintaining cell integrity and proper function.
