http://medcell.med.yale.edu/lectures/introduction_cell_membrane.php WebMost integral membrane proteins span the cell membrane, so they have both hydrophilic and hydrophobic regions. Second, peripheral membrane proteins are temporarily associated with the membrane and can easily be experimentally separated. These proteins can be associated with either the internal or external side of the membrane.
