Which type of membrane protein is anchored to the lipid bilayer by a lipid tail?

Lipid-anchored proteins are a specific type of membrane protein that are attached to the lipid bilayer through a covalent bond with a lipid tail. This lipid tail allows them to anchor themselves to the membrane, providing stability and ensuring their presence at the membrane surface. Unlike integral proteins, which span the membrane, or peripheral proteins, which are loosely associated with the membrane surface, lipid-anchored proteins are tethered to the membrane through their lipid components. Their anchoring can play crucial roles in cellular signaling and membrane dynamics. This is what distinguishes them and makes the answer correct for the given question about membrane protein types.
