Document Summary
The extracellular matrix is made and oriented by the cell within it. Macromolecules that in the extracellular matrix are normally produced in the extracellular. Connective tissue is divided into two main classes. Glycosaminoglycan (gag) chains occupy large amounts of space and form hydrated. Glycosaminoglycan: unbranched polysaccharide chains composed of repeating sugar contains amino acid and is usually sulfated. The other sugar is usually uronic acid (glucuronic, iduronic) These polysaccharides are hard to fold and form large masses. Hyaluroman acts as a space filler and faciliator of cell migration during tissue. Proteoglycans are composed of gag chains covalently linked to a core protein. Elastic fibres: gives the tissues extra strength.
