Glucosamine hydrochloride (D-Glucosamine hydrochloride) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids, is used as a dietary supplement. Glucosamine hydrochloride also is a natural constituent of glycosaminoglycans in the cartilage matrix and synovial fluid, which when administered exogenously, exerts pharmacological effects on osteoarthritic cartilage and chondrocytes^[1].

Glucosamine hydrochloride (D-Glucosamine hydrochloride) exhibits dose-dependent DPPH antioxidant activity^[2].
Glucosamine hydrochloride treatment of Short-term (4 h) inhibits HIF-1α at the protein level, decreases phosphorylation of p70S6K and S6, translation-related proteins^[3].
Glucosamine hydrochloride significantly decreases renal expression of α-smooth muscle actin, collagen I, and fibronectin in the obstructed kidneys and TGF-β1-treated renal cells^[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
