Cell and ECM Macromolecular Structure

All cells found in ECM are complex organizations of macromolecules. They are arranged in such a manner as to allow small molecules and ions to diffuse into the cell and for these components to be synthesized into macromolecules used in forming structural materials within and outside the cell. Macromolecules are made up of long chains of repeat units that are connected end to end in the form of proteins, nucleic acids, lipids, and polysaccharides.
