The cell membrane regulates the flow of materials in and out of the cell. Membrane sidedness is an important concept in cell biology because to gives a better understanding on how the cell membrane functions.
The two major chemical compounds found in a membrane are phospholipids and proteins. Phospholipids make up the bilayer structure of the membrane, while proteins serve various functions such as transport, signaling, and support within the membrane.
The two organelles that are double membranous are the mitochondria and the chloroplasts. They both have an outer membrane and an inner membrane, which helps compartmentalize their functions within the cell.
