Hyaluronan (HA)

Target
HA
Molecular classification
Glycosaminoglycan, Extracellular matrix component, Polysaccharide
01

Overview

Hyaluronan is a high-molecular-weight polysaccharide essential for structural support within tissues due to its unique physicochemical properties. Its roles span from joint lubrication and skin hydration to facilitating cellular processes critical during development or repair. Medically it is widely used both therapeutically—in joint disease—and cosmetically—as a filler or moisturizer. Ongoing research continues exploring new therapeutic applications based on its biocompatibility and ability to interact with cells/molecules across biological systems.
