Hyaluronic Acid

Hyaluronic acid, also called hyaluronan, is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is unique among glycosaminoglycans as it is non-sulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large: human synovial HA averages about 7 million Da per molecule, or about 20,000 disaccharide monomers, while other sources mention 3–4 million Da. · Glucuronic acid · N-Acetylglucosamine · Serenoa · Glycolic acid · Moisturizer · heparin (porcine) · niacinamide · Ceramide · Keratan sulfate · salicylic acid
