Permeability coefficients (cm/sec) for the passage of various molecules through synthetic lipid bilayers

Range	Figure link - link cm/sec
Organism	Generic
Reference	Alberts, Molecular biology of the cell, 3rd edition, 1994, chapter 11, p.509 fig.11-2
Comments	Lipid bilayers are highly impermeable to charged molecules (ions), no matter how small: the charge and high degree of hydration of such molecules prevents them from entering the hydrocarbon phase of the layer. See note beneath table
