What affects the permeability of a lipid bilayer?

Solution

Solution:
Lipid bilayer is a membrane that is made up of two layer of lipids.It helps cell in maintaining shape.Lipid bilayer act like barrier around the cell.Various types of molecules needed for proper cell function are transported through it.Permeability of lipid bilayer is affected by various factor.One of the factor is size of molecules.Small molecule can pass easily through it in comparison to large molecules.Other factor is charge on molecules.Lipid bilayer have electrically charged head and neutral tail.It is suitable for neutrally charged molecule to pass through it easily.But charged molecule not able to cross it.
