What Are Lipid Rafts in Cell Membranes?

💡 The Answer

• Lipid rafts are specialized microdomains enriched with cholesterol and sphingolipids.
• They serve as platforms for cell signaling and protein sorting.
• Membrane rafts are more ordered and less fluid than surrounding areas.
• They help concentrate receptors and signaling molecules.
• Rafts are involved in endocytosis and membrane trafficking.
