Unformatted text preview: molecules, and, as we will discuss later, it also contains proteins. The bilayer's fluidity allows these structures mobility within the lipid bilayer. This fluidity is biologically important, influencing membrane transport. Fluidity is dependent on both the specific structure of the fatty acid chains and temperature (fluidity increases at lower temperatures). Structurally, the lipid bilayer is asymmetrical: the lipid and protein composition in each of the two layers is different....
