Cholesterol is found in every cell of your body. It is especially abundant in the membranes of these cells, where it helps maintain the integrity of these membranes, and plays a role in facilitating cell signaling-- meaning the ability of your cells to communicate with each other so you function as a human, rather than a pile of cells.
the membrane to stay fluid more easily when cell temperature drops
Maintains membrane fluidity
why are cholesterol molecules important components of cell membranes
Yes - cholesterol is found in cell membranes. Cholesterol helps to stabilise the membrane. It is also sometimes involved in cell signalling.
Phospholipids, cholesterol, & glycolipids.
Cholesterol molecules and protein molecules help stabilize the cell membranes. Cholesterol prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. Cholesterol is only found in animal cells.
The basic structure of all membranes is the same. They are composed of two layers of phospholipid molecules, associated with other molecules including proteins, carbohydrates and cholesterol. I hope this helps.

Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.
