Nicolson's theory of membrane structure

Nicolson's theory, also known as the fluid mosaic model, describes cell membranes as dynamic, flexible structures composed of a bilayer of lipids with embedded proteins. These lipids form a semi-fluid barrier, allowing the membrane to be flexible and self-healing. Proteins are scattered throughout, serving functions like transport and communication. This structure enables the membrane to be selectively permeable, controlling what enters and exits the cell, and maintains the integrity and flexibility necessary for cell function. Overall, it portrays the membrane as a fluid, functioning mosaic of lipids and proteins working together.
