cholesterol is an integral part of plasma membranes. based on its structure, where is it found in the membrane?

Cholesterol is embedded between the phospholipid tails in the interior (hydrophobic region) of the lipid bilayer, with its small hydroxyl (-OH) group near the phospholipid head groups.

In simple exam-style terms, the best answer is:

• It is found within the phospholipid bilayer, interspersed among the fatty acid tails, not on the surface of the membrane.
