Explanation:
Detailed explanation-1: -Glycolipids are membrane carbohydrates linked to lipids. These carbohydrate chains help in cell-to-cell recognition.
Detailed explanation-2: -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-3: -Complex carbohydrates coat the surfaces of cells and have the potential to carry the information necessary for cell-cell recognition. Sugar-specific receptors (lectins) are also present on cells, and can interact with sugars on apposing cells.
