Glycosaminoglycans

Glycosaminoglycans

A) are complex polysaccharides that contribute to the hydration and porosity of the extracellular matrix.
B) are composed of repeating disaccharide units with a strong positive charge that attracts water and so provides cushioning against external forces.
C) are adhesive proteins that anchor cells to fibres within the extracellular matrix.
D) are structural proteins that allow the extracellular matrix to stretch and rebound without damage.
E) combine with structural proteins to form cross-linked fibres that allow the extracellular matrix to resist tension.
