Integral membrane proteins Amphipathic Properties Also referred to as transmembrane proteins. Commonly, integral membrane proteins have membrane spanning domains which are alpha helical. May be 1 , 2, 7 or more membrane spanning alpha helical domains. The alpha helix neutralizes the polar character of the peptide bonds. The hydrophobic side chains assoc. with these amino acids interact with the fatty acid chains of membrane

Unformatted text preview: lipids. Most transmembrane proteins are also glycosylated [have carbohydrate groups attached] Peripheral membrane proteins Not embedded in the bilayer but indirectly associated with the membrane through interactions with integral membrane proteins or by weak electrostatic interactions with the hydrophilic head groups of membrane lipids. Located extracellular or associated with the cytoplasmic surface of the bilayer....
