proteoglycans

Bimolecule complexes of proteins and GLYCOSAMINOGLYCANS with a high proportion of carbohydrate (up to 96 per cent) to protein. They are structural components of connective tissues and lubricants, help in the adhesion of cells to the extracellular matrix, and bind factors that promote cell proliferation.

proteoglycans (prō´tēōglī´kans),

n.pl the mucopolysaccharides bound to protein chains occurring in the extracellular matrix of connective tissue.
