In this video, I talk about the structure and functional features of glycosaminoglycan.
Glycosaminoglycans[1] (GAGs) or mucopolysaccharides[2] are long unbranched polysaccharides consisting of a repeating disaccharide unit. The repeating unit (except for keratan) consists of an amino sugar (N-acetylglucose amine or N-acetylgalactose amine) along with a uronic sugar (glucuronic acid or iduronic acid) or galactose.[3]
Glycosaminoglycans have high degrees of heterogeneity with regards to molecular weight, disaccharide construction, and sulfation due to the fact that GAG synthesis, unlike proteins or nucleic acids, is not template driven, and dynamically modulated by processing enzymes
