Generally drugs can act on the level of different biological membranes as well as inside the cells that are limited by membranes. Even in the latter situation, drugs must still interact with the membrane in order to cross it and reach their targets. For this reason, the efficiency of drugs to interact with the membranes constitutes ...
WebThis cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out. Structure and Composition of the Cell Membrane. The cell membrane is an extremely pliable structure composed primarily of back-to-back phospholipids (a “bilayer”). Cholesterol is also present, which contributes to the fluidity ...
