Carbohydrates are also vital components, attached to lipids (forming glycolipids) or proteins (forming glycoproteins) on the extracellular surface. Peripheral proteins, on the other hand, are attached to the surface of the membrane, either on the exterior or interior.
How Cholesterol Shapes Membrane Fluidity and Function
This selective permeability is crucial for maintaining homeostasis. The structure of a cell membrane is a fundamental concept in biology, defining the physical boundary that separates the internal components of a cell from its external environment.
Processes like endocytosis and exocytosis rely on the membrane's ability to invaginate and fuse, allowing the cell to ingest large particles or export waste and signaling molecules. Nicolson in 1972, remains the most widely accepted explanation of the cell membrane's structure.

These carbohydrate chains are essential for cell recognition, adhesion, and immune response, acting as identification tags that distinguish "self" from "non-self. The "mosaic" aspect refers to the diverse array of proteins scattered throughout the lipid bilayer, much like tiles in a mosaic pattern.
