Why do cell membranes have a lipid bilayer instead of a monolayer?

WebCellular membranes are made up of lipid bilayers. As a reminder, all biological membranes are made up of lipid bilayers with ≈ 30 Å hydrophobic thickness. The headgroups are polar and charged and add an additional ≈ 10 Å to the total membrane thickness. The lipid bilayer structure arises from the WebMembrane proteins are broadly classified as transmembrane (TM) or peripheral, with functions that pertain to only a single bilayer at a given time. Here, we explicate a class of proteins that contain both transmembrane and peripheral domains, which we dub transmembrane membrane readers (TMMRs).
