Carrier protein

Patent Pending Carrier proteins facilitate the diffusion of different molecules, while channel proteins are involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane.[1] Carrier proteins are integral/intrinsic [2] membrane proteins; that is they exist within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion or active transport. These mechanisms of movement are known as carrier-mediated transport.
