Figure 1 summarizes the permeability properties of pure lipid bilayers. Lipid-soluble molecules can readily pass through a lipid bilayer. Examples include gas molecules such as oxygen (O 2) and carbon dioxide (CO 2), steroid molecules, and fat-soluble vitamins (A, D, E, and K). Surprisingly, some small polar molecules are capable of permeating the lipid bilayer without the aid of a membrane transport protein.
permeable to polar molecules and ions, which is discussed below.) All in all, relatively few kinds of endogenous molecules cross membranes by lipid diffusion. However, most drugs are small amphipathic compounds, and therefore rely. heavily on lipid diffusion to move through different compartments in the body. The ability of drugs to diffuse across membranes is heavily inï¬uenced by the. ionizability of the drug in the surrounding medium.
