Glycosaminoglycan (GAG)

Definition

Glycosaminoglycans (GAGs) are long unbranched polysaccharides composed of repeating disaccharide units that are major structural components of the extracellular matrix. GAGs including hyaluronic acid, chondroitin sulfate, and dermatan sulfate provide hydration, cushioning, and signaling functions in connective tissue. GHK-Cu has been shown to stimulate glycosaminoglycan synthesis, contributing to its wound healing and tissue remodeling properties.
