Glycosaminoglycan

Molecular classification: Polysaccharide

Overview

Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long, linear, negatively charged polysaccharide molecules composed of repeating disaccharide units. They play crucial roles in structural support, cell signaling, and lubrication in various tissues. Their interactions with proteins are essential for diverse biological processes, and defects in their degradation lead to lysosomal storage disorders. Heparin, a highly sulfated GAG, is widely used as an anticoagulant.

Other names: GAGMucopolysaccharide

Mechanism of action

Heparin acts as an anticoagulant by enhancing antithrombin activity.
