Diagram of Cell Membrane Structure

This diagram thoughtfully illustrates the intricate architecture of a cell membrane. Starting from a basic cell overview, it meticulously zooms in to reveal the complex arrangement of the cell's outer boundary. We can observe the double layer of lipids, known as the phospholipid bilayer, acting as the fundamental framework. Embedded within this layer, or associated with it, are various proteins, some spanning the entire membrane and others attached to its surfaces. Sugars linked to lipids (glycolipids) and proteins (glycoproteins) are visible on the exterior, playing crucial roles in cell recognition. The presence of cholesterol within the lipid layers helps maintain membrane fluidity. Furthermore, connections to the underlying cytoskeleton are shown, highlighting the membrane's structural support and dynamic capabilities. A closer look provides an even more detailed view of the phospholipid bilayer, finally isolating a single phospholipid molecule to show its distinct hydrophilic head and hydrophobic tails.
