A hydroxyl group of glucose is replaced by an amino group. Molecular formula C6H13O5N, commonly known as amino sugar, referred to as ammonia sugar. Gold chitosan glucosamine hydrochloride is also known as glucosamine, which is widely found in nature. 2- amino -2- deoxy -D- glucose is usually found in the form of N- acetyl derivatives (such as chitin) or N- sulfate and N- acetyl -3-O- lactate (cell wall acid) in the polysaccharide and binding polysaccharide derived from microbial and animal origin.

The alpha glucosamine is acicular crystallization, the melting point is 88 degrees centigrade, +100 degree to 47.5 degree (water), the beta type is acicular crystallization, the melting point is 110 degrees C (decomposition), +28 degree to +47.5 degree (water); it is dissolved in water. 2- amino -2- deoxy -D- glucose is a component of a variety of antibiotics.

Glucosamine, which is synthesized in human body, is an important nutrient for chondrocyte formation, and is a natural tissue component of healthy articular cartilage. As age increases, the lack of glucosamine in the body is becoming more and more serious, and articular cartilage is deteriorating and worn. Numerous medical studies in the United States, Europe and Japan have shown that glucosamine can help repair and maintain cartilage and stimulate the growth of chondrocytes.
