N-Acetyl-D-Glucosamine (NAG), CAS number 7512-17-6, is the basic building block of many important polysaccharides in biological cells, especially in the exoskeletons of crustaceans, where it is most abundant. It is an important prerequisite for the synthesis of bifidogenic factors and has many important physiological functions in living organisms. For example, N Acetyl D Glucosamine can be used as a monomer of chitin, which is linked by β-1,4-glycosidic bond to form chitin. N-Acetyl Glucosamine is a white powder. It is easily soluble in water. N Acetyl Glucosamine has anti-inflammatory, anti-tumour and antioxidant effects, and is clinically used in the treatment of osteoarthritis and rheumatoid arthritis. It is widely used in the fields of food, medicine and cosmetic, etc. It can be used as an antioxidant for food and as an additive for food for infants and young children, and as a sweetener for people suffering from diabetes mellitus.
