What Kind Of Molecule Forms A Bilayer That Is The Basis For All Cellular Membranes? Fatty Acids and Eicosanoids. Fatty acids are vital for life in that they constitute integral components of tissue membranes, have the highest energy density of all energy substrates, are precursors for innumerable lipid mediators and modulate protein function through post-translational acylations (proteolipids).Fatty acids can also be considered as one of the defining constituents of lipids.
