The main difference between intermolecular and intramolecular forces is that intermolecular forces exist between the molecules themselves, whereas intramolecular forces exist between atoms within a molecule. Intermolecular forces are formed between molecules and, intra-molecular forces are formed within the molecule. • Intra-molecular forces are much stronger compared to intermolecular forces.
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.
