Pure Hyaluronic Acid

Pure Hyaluronic Acid (HA) is a naturally occurring, high‑molecular‑weight glycosaminoglycan composed of repeating disaccharide units of D‑glucuronic acid and N‑acetyl‑D‑glucosamine. In supplement form it is used primarily to support extracellular‑matrix (ECM) integrity, joint lubrication, and skin hydration, thereby supporting musculoskeletal health, skin appearance, and cellular signaling.

Hyaluronic acid is a linear, non‑sulfated glycosaminoglycan: (C₁₄H₂₁NO₁₁)n (repeating disaccharide). The IUPAC name for the repeating unit is **[(2‑S‑3‑hydroxy‑4‑octyl‑2‑hydroxy‑5‑(2‑hydroxy‑3‑[(2‑hydroxy‑2‑oxo‑1‑oxo‑2‑hydroxy‑2‑hydroxy‑1‑(2‑hydroxy‑2‑hydroxy‑2‑hydroxy‑1‑hydroxy‑2‑hydroxy‑2‑hydroxy‑1‑hydroxy‑2‑hydroxy‑2‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy‑1‑hydroxy
