Networks for Transport Across Membranes

Part of the Universitext book series (UTX)


According to the generally accepted “unit membrane model” established by Danielli and Davson in 1935, a biological membrane may be considered as a double layer of lipid molecules. The characteristic feature of the lipids is their hybrid structure consisting of a polar head group to which a twofold hydrocarbon chain is attached. When forming a membrane, the lipids of the two layers are brought into contact with their hydrocarbon layers thus creating a hydrocarbon and hence hydrophobic phase in the membrane interior. The polar head groups at the exterior surfaces of the membrane are covered by layers of specific structural membrane proteins. The thickness of the whole membrane is of the order of 100 A.
