- 3.6: Lipids and Signaling
- Lipids are not just used as a passive component of membranes, or as a source of stored energy. They are involved in the process of signal transduction at the cell membrane, a process by which the interior components of the cell respond to a signal external to the cell, allowing the cell to respond to their local environment. Usually a chemical signal on the outside of the cell is the "primary messenger" that causes the cell to respond.
