Glucosamine (C6H13NO5) is also called as glucosamine, glucamine, or aminoglucose, which is a kind of compound after a hydroxyl of glucose is replaced by amidogen. Glucosamine is an important precursor in protein or fat glycosylation reaction. Glucosamine derivative N-acetylglucosamine is a monomer of chitin, and chitin is widely existed in exoskeleton and fungal cell wall of arthropods. Another derivative N- acetyl muramic acid is the basis of bacterial cell wall. Glucosamine is one of monosaccharide with the most abundant content in nature. In industry, glucosamine is formulated with the use of exoskeleton of shellfishes. Glucosamine is generally used as food for cure of osteoarthritis.
Mainly applied in medical supplies. It has important physiological functions on human bodies, participating in liver and kidney detoxification, playing an role in anti-inflammatory and liver protection, stimulating the growth of bacillus in infants’ intestinal tracts, having favorable curative effects on curing rheumatic inflammation and gastric ulcer, and restraining cell growth. It is the major raw material for compounding antibiotics and anti-cancer drugs. It can also be applied as additives of food, cosmetics, and feed, with very wide application.
