membranene
Membranene are flexible, lipid-protein layers that enclose cells and their organelles. They create distinct compartments, regulate the movement of ions and molecules, and facilitate communication and signaling. The plasma membrane forms the boundary of the cell, while intracellular membranes define the compartments within the cytoplasm.
Most membranes consist of a phospholipid bilayer in which amphipathic lipids arrange with hydrophilic heads outward
Various membranes perform diverse functions. Nuclear envelope encloses the genome; endoplasmic reticulum and Golgi apparatus synthesize
Membrane biology is central to health and disease; defects in transporters or fusion proteins cause disorders.
