Glycosaminoglycan
Polysaccharides found in animal tissue / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Glycosaminoglycan?
Summarize this article for a 10 year old
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 due to enzyme deficiencies.
