Acetylglucosamine (N-acetyl-D-glucosamine) is an aminosaccharide that is a key component of the cell walls of insects, fungal walls and the exoskeletons of some animals, including crustaceans and insects. It is also an essential building block of polysaccharides such as chitin and hyaluronan and is found on the cell surface in mammalian bodies. N-acetylglucosamine is used for its potential anti-inflammatory and anti-arthritic effects, as an ingredient in foods and dietary supplements to increase joint mobility and to improve skin and hair health.

N-acetyl-D-glucosamine is commonly used in cosmetic products due to its moisturising and hydrating properties, as well as its ability to strengthen the skin's natural barrier. Skin care products such as creams, lotions and serums often contain this amino saccharide. It can also be found in some make-up products and sunscreens. In the food industry, it is used as a sweetener and stabilizer in bakery and beverage production. In the pharmaceutical industry, N-acetyl-D-glucosamine is used as a natural remedy for osteoarthritis and other joint diseases. It is also being considered for possible use in the treatment of digestive and intestinal disorders, including irritable bowel syndrome and ulcerative colitis.
