Concept explainers
To explain: The negatively charged glycosaminoglycan polysaccharide chains establish a hydrated gel-like environment around the cell.
Concept introduction: Glycosaminoglycans are the polysaccharide chains consisting of disaccharide monomer units. They are negatively charged chains that are covalently linked to protein molecules to form proteoglycans. These form extracellular matrix formed by interwoven protein fibers with glycosaminoglycan chains.
To explain: How do the properties vary if polysaccharide chains were uncharged?
