What is the composition of the lysosomal membrane?

The lysosomal membrane is composed of a double membrane, which is typical of various organelles within eukaryotic cells. This double lipid bilayer structure helps to separate the contents of the lysosome from the cytosol, allowing it to maintain an acidic internal environment necessary for the activation of various hydrolytic enzymes. These enzymes play a crucial role in breaking down macromolecules, old cellular components, and foreign materials. The double membrane not only protects the rest of the cell from these potentially harmful enzymes but also supports the lysosome in its functional role as the cell's waste disposal system.
