N-acetyl D-Glucosamine

N-acetyl-D-glucosamine (GlcNAc, NAG) is an amino sugar, the N-acetylated derivative of glucosamine and the repeating monomer unit of chitin, supplied by Nustras as a white crystalline powder for the supplement, functional food and cosmetic markets. It is also a structural unit of hyaluronic acid and other glycosaminoglycans.

It is formulated into supplements in capsule, tablet and powder form, into functional foods and beverages, and into cosmetic and personal-care preparations as a humectant and conditioning ingredient.

The material is a white crystalline powder, freely soluble in water, with a slightly sweet taste. CAS 72-87-7, molecular formula C8H15NO6, molecular weight 221.21. Assay, specific rotation, loss on drying, residue on ignition and pH are standardised to specification; identity is confirmed by infrared spectroscopy and high-performance liquid chromatography, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. The source material (chitin from crustacean shell, or fermentation) is stated on the specification; buyers requiring a shellfish-free or vegetarian source confirm this at ordering.

Nustras supplies N-acetyl-D-glucosamine in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. N-acetyl-D-glucosamine is an accepted supplement and cosmetic ingredient in major markets; buyers confirm the permitted level and claim for their application.
