Which among the following is the main content of lipid bilayer of cell membrane in animal cells?
Correct Answer: Cholesterol
Description: The most common sterol in the membranes of animal cells is cholesterol, which resides mainly in their plasma membranes, but can also be found in lesser quantities in mitochondria, Golgi complexes, and nuclear membranes. Cholesterol intercalates among the phospholipids of the membrane, with its hydroxyl group at the aqueous interface and the remainder of the molecule within the leaflet. Ref: Murray R.K., Granner D.K.
