WebThe cell surface and connective matrix of animal tissues have large proteoglycan molecules, which have covalently attached glycosaminoglycan chains (GAGs) that may be either N-linked or O-linked to the core protein. GAGs are linear polysaccharides that consist of repeating disaccharide units of hexuronic acid linked to a hexosamine. Proteoglycans are proteins that are heavily glycosylated. The basic proteoglycan unit consists of a "core protein" with one or more covalently attached glycosaminoglycan (GAG) chain(s). The point of attachment is a serine (Ser) residue to which the glycosaminoglycan is joined through a tetrasaccharide bridge (e.g. chondroitin sulfate-GlcA-Gal-Gal-Xyl-PROTEIN).
