What type of amino acids will be present where integral proteins attach to cell membranes?

The stretch of the integral protein within the hydrophobic interior of the bilayer is also hydrophobic, made up of non-polar amino acids. Like the lipid bilayer, the exposed ends of the integral protein are hydrophilic. When a protein crosses the lipid bilayer it adopts an alpha-helical configuration.
