Integral Membrane Proteins
Imbedded in the lipid bilayer, with hydrophobic
association with the lipid hydrocarbon chains
Can only be removed from the membrane with
organic solvents or detergents
Pure protein in absence of detergent is insoluble
Can be transmembrane, or can face only one side
of membrane
Glycophorin (Fig. 9.14), bacteriorhodopsin (Fig.
9.15), maltoporin (Fig. 9.16) are examples
