What Is the Significance of the Lipid Bilayer's Thickness?

💡 The Answer

• The thickness of a typical lipid bilayer is about 5–8 nanometers, matching protein hydrophobic spans.
• Mismatch can cause membrane distortion or protein aggregation to relieve stress.
• Thickness varies with fatty acid chain length and saturation, affecting protein function.
• The value is critical for membrane protein orientation and ion channel gating.
