How does cholesterol hold channels?

Cholesterol plays a critical role in maintaining the structure of cell membranes by holding channels in place. As discussed by Andrew Huberman and Peter Attia on the Huberman Lab, cholesterol is necessary for life and is a key component of cell membranes.

Cell membranes are not rigid structures; they are fluid and dynamic, allowing them to morph and move. Cholesterol, along with phospholipids, provides the structural integrity required for cells to maintain their shape and form channels across their membranes. These channels are essential for various cellular functions, including the transport of molecules and signaling processes 1.
