permeabiliteettikalvo
Permeabiliteettikalvo refers to a membrane that allows certain substances to pass through while restricting the passage of others. This selective permeability is a crucial property for many biological and synthetic systems. In biological contexts, cell membranes are prime examples of permeabiliteettikalvo. These membranes, composed primarily of a lipid bilayer with embedded proteins, regulate the movement of ions, nutrients, and waste products into and out of the cell, maintaining homeostasis. The specific proteins embedded within the membrane, such as ion channels and transport proteins, play a vital role in determining which substances can cross and under what conditions.
Synthetic permeabiliteettikalvot are engineered materials designed to mimic or enhance the selective properties of natural membranes.
