Chemical Name: 2-Amino-2-deoxy-D-glucose
Molecular Formula: C₆H₁₃NO₅, Molecular Weight
Structure: The C2 hydroxyl group of glucose is replaced by an amino group, with two configurations
Appearance: White to off-white needle-like crystals
Melting Point: α-form 88℃; β-form 110℃ (decomposes)
Solubility: Easily soluble in water, slightly soluble in methanol and ethanol, insoluble in ether and chloroform
Stability: Stable at room temperature and dry; easily decomposes in strong acids/bases; requires sealed storage away from light.
Repairing and synthesizing cartilage: Serving as a raw material for the synthesis of cartilage matrix proteoglycans and type II collagen, it stimulates chondrocyte proliferation, increasing cartilage thickness and elasticity.
Anti-inflammatory and analgesic: Inhibits pro-inflammatory factors such as IL-1β and TNF-α, as well as matrix metalloproteinases (MMPs), reducing cartilage degradation and synovial inflammation.
Lubricating joints: Promotes synovial secretion of hyaluronic acid, improves the viscoelasticity of synovial fluid, and reduces joint friction.
Protecting joint structure: Delays joint space narrowing and inhibits the progression of osteoarthritis.
