Can proteins flip flop
WebDec 29, 2024 · Flippases are transmembrane proteins that facilitate movement of lipids across cellular membranes. Energy-independent flippases (also called scramblases) randomize the distribution of lipids across the bilayer by facilitating bidirectional movement of lipids between membrane leaflets.

WebMost of the lipids and some of the proteins can drift about laterally – that is, in the plane of the membrane. It is quite rare; however, for a molecule to flip-flop transversely across the membrane, switching from one phospholipids layer to the other; to do so, the hydrophilic part of the molecule must cross the hydrophobic core of the membrane.
