Detailed explanation-1: -Carbohydrates covalently linked to proteins (glycoproteins) or lipids (glycolipids) are also a part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilayer with floating proteins and carbohydrates.

Detailed explanation-2: -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-3: -Phospholipids are the major component of cell membrane to form lipid bilayers. Figure 21.1 shows the representative structure of common lipids (Gunstone et al., 2007). 21.1.

Detailed explanation-4: -Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.
