Why Does the Phospholipid Bilayer Act Like a Liquid Crystal?

💡 The Answer

• Phospholipid tails are disordered like a liquid, while heads remain ordered like a solid.
• This dual nature allows the bilayer to flow and self-heal while maintaining barrier function.
• Temperature changes can shift the bilayer from gel to fluid phase, altering membrane properties.
• Living organisms use cholesterol to fine-tune this liquid crystalline state for optimal function.
