Detailed explanation-1: -In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. The glycolipids are found exclusively in the outer leaflet of the plasma membrane, with their carbohydrate portions exposed on the cell surface.

Detailed explanation-2: -Acting as essential building blocks of the plasma membranes, cholesterol plays pivotal roles in maintaining the structural integrity and regulating the fluidity of cell membranes [17–20], therefore contributing to the homeodynamics of various membrane proteins on the cell surface.

Detailed explanation-3: -The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.

Detailed explanation-4: -The plasma membrane is made up primarily of a bilayer of phospholipids with embedded proteins, carbohydrates, glycolipids, and glycoproteins, and, in animal cells, cholesterol.

Detailed explanation-5: -Protein channels. Transmembrane proteins. Peripheral proteins. Glycoproteins. Glycolipids. Filaments of cytoskeleton are found along the cytoplasmic side of the membrane and provide a scaffolding for the membrane. 04-Sept-2021
