Proteoglycans, glycoproteins and peptidoglycans are hybrid molecules in witch the saccharide and peptide components are linked covalently. In proteoglycans the polypeptide chain is substituted by covalently linked polysaccharide chains, whereas in glycoproteins the-polypeptide chains bear covalently linked oligosaccharides. In the peptidoglycans polysaccharide chains are substituted by oligopeptides which may be covalently cross-linked.
