Study Notes
Amphipathic Molecules
- Amphipathic molecules have both hydrophobic and hydrophilic regions.
- These molecules are essential for forming cell membranes.
Lipid Bilayers
- Lipid bilayers are composed of amphipathic molecules.
- The hydrophobic tails of these molecules face inwards, creating a barrier to water-soluble compounds.
- The hydrophilic heads face outwards, interacting with the aqueous environment.
- These membranes are stable and low in energy, ensuring the integrity of cellular structures.
Hydrophobic Compounds and Equilibrium
- Hydrophobic compounds can easily pass through lipid bilayers.
- This is because the hydrophobic tails of the lipids readily interact with the hydrophobic compounds.
- This allows for rapid equilibrium across the membrane.
Lipids as Barriers
- Lipid bilayers form effective barriers to many compounds.
- This is essential for maintaining cellular integrity and regulating the passage of molecules.
- Lipids can impede the movement of hydrophilic molecules, which have difficulty passing through the hydrophobic core of the membrane.
