Do carbohydrates only bind to the extracellular space? If so, please elborate as to why that occurs.

Solutions

Expert Solution

Answer is No.

Explanation:-

  • Cell membranes are selective barriers that separate individual cells and cellular compartments.
  • Membranes are assemblies of carbohydrates, proteins, and lipids held together by binding forces.
  • Carbohydrates are covalently linked to proteins (glycoproteins) or lipids (glycolipids) and also an important 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.
  • Membrane carbohydrates are chemically bound to glycolipids and glycoproteins.
  • However, some membrane carbohydrates are part of proteoglycans that insert their amino acid chain among the lipid fatty acids.
  • Although some carbohydrates can be found associated with intracellular membranes, most of them are located in the outer monolayer of the plasma membrane, facing the extracellular space.
