Glycosaminoglycans (GAGs) are negatively charged polysaccharide compounds composed of repeating units of uronic acid and hexosamine. This structure makes GAGs hydrophilic, forming a gel-like network structure in the extracellular matrix, providing tissue support and lubrication. It is present in almost all mammalian tissues and is involved in tissue structure maintenance, cell signaling, and the regulation of biomacromolecules. CD BioGlyco provides clients with highly purified GAG products to meet the applications in glycobiology, bioengineering, regenerative medicine, cancer research, etc. web: https://www.bioglyco.com/hot-glycans/glycosaminoglycans.html
