Fatty Acid structure

Fatty Acid chains in membrane

Short chain length and unsaturation enhance the fluidity of fatty acids and their derivatives by lowering melting point.

3 main types of membrane lipids

- Phospholipids


- Glycolipids


- Cholesterol

What do Glycolipids and Phospholipids do?

Glycolipids and Phospholipids readily form bimolecular sheets in aqueous membrane.



The driving force is ther hydrophobic interactions among fatty acid tails of membrane lipids.

What is faster, lateral or transverse diffusion?

Lateral diffusion is faster than transverse diffusion.
