General description

Chondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans. Chondroitin sulfate B (Dermatam sulfate) is a component of proteoglycans such as decorin, biglycan and versican. Chondroitin sulfate B is used to study β peptide (1-42) cytotoxicity.

Application

Chondroitin sulfate B may be used to study its roles as a biomolecule receptor, mediator of cell signaling and cell binding molecule. It may be used to compare its properties to those of chondroitin sulfate A and chondroitin sulfate C. Chondroitin sulfate B is used to study β peptide(1-42) cytotoxicity.

Biochem/physiol Actions

As a large, negatively charged, hydrophilic molecule that is too inflexible to fold into a compact globular structure, chondroitin sulfate molecules form porous hydrated gels, providing mechanical support to tissue and allowing rapid diffusion of water-soluble molecules and migration of cells.

Components

Chondroitin Sulfate B is an acidic mucopolysaccharide found in cartilage, skin, cornea, and umbilical cord. It is composed of alternating N-acetylgalactosamine, L-iduronic acid, and sulfate residues in equimolar quantities where carbon 4 of the N-acetylgalactosamines is sulfated.

Caution

One mechanism leading to neurodegeneration during Alzheimer's disease (AD) is amyloid beta peptide (Abeta)-induced neurotoxicity. Among the factors proposed to potentiate Abeta toxicity is its covalent modification through carbohydrate-derived advanced glycation endproducts (AGEs). Other experimental evidence, though, indicates that certain

Glycosaminoglycans and Proteoglycans

There are five identified glycosaminoglycan chains (see Figure 1): Hyaluronan is not sulfated, but the other glycosaminoglycan chains contain sulfate substituents at various positions of the chain.

Glycosaminoglycan Sulfation and Signaling

Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.
