Glycosaminoglycans (GAGs), the glycan part of the proteoglycan, are classified into several categories based on the type of the so-called “repeating disaccharide” moieties which consist of hexosamine and hexuronic acid. The repeating disaccharide region occupies most of the GAG. A variety of the GAG biological activities is controlled by the complex, but a minute structure of the repeating oligosaccharides including the regiospecific sulfate groups. GAGs obtained from nature have heterogeneous structures. On the other hand, chemically synthesized GAGs have well-defined structures in a molecular level, and sufficient amounts can be supplied. To study the chemical, biological, medical as well as physical performance of the GAGs, a synthetic approach is strongly recommended. This chapter describes the synthesis of the GAG oligosaccharides focusing on the repeating region.
