WebOct 16, 2015 · Hyaluronic acid (HA), known as hyaluronan or hyaluronate, is a natural occurring, non-toxic, biocompatible and biodegradable polysaccharide. HA is a unique non-sulfated glycosaminoglycan composed of disaccharide repeating units of β-1,4- d -glucuronic acid and β-1,3- N -acetyl- d -glucosamine [ 10 ]. WebHyaluronic acid (HA) is among the simplest of large glycan structures, composed of just two sugars, glucuronic acid (GlcA) and N-acetylglucosamine (GlcNAc), in an unbranched repeating chain (GlcA β1–3 GlcNAc β1–4)n ( Hascall and Esko, 2024 ).
