Membrane biology

Membrane biology studies the membranes that surround and protect cells, acting like selective barriers. These membranes are primarily made of lipids and proteins, allowing certain substances to enter or exit the cell while keeping others out. This selective permeability is crucial for maintaining a stable internal environment, known as homeostasis. Membranes also facilitate communication between cells and allow them to interact with their environment. Understanding membrane biology is essential for various fields, including medicine, as it influences drug delivery, disease mechanisms, and cellular functions.
