Cholesterol is an integral part of plasma membranes. based on its structure, where is it found in the membrane?
on the extracellular surface
embedded with the phospholipid heads
within the tail bilayer
attached to the intracellular surface

The correct option is : b. embedded with the phospholipid heads

Explanation:

Plasma membrane, also called the cell membrane, is a biological semi permeable membrane that surrounds the cell.

The plasma membrane is composed of lipids, proteins and carbohydrate groups.
