Polysaccharides found in animal tissue

Glycosaminoglycans[1] (GAGs) or mucopolysaccharides[2] are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a galactose unit.[3] GAGs are found in vertebrates, invertebrates and bacteria.[4] Because GAGs are highly polar molecules and attract water; the body uses them as lubricants or shock absorbers.

Mucopolysaccharidoses are a group of metabolic disorders in which abnormal accumulations of glycosaminoglycans occur du...
