Quick Summary

Glucosamine is an amino derivative of glucose, with the chemical formula C₆H₁₃NO₅. It is a component of various polysaccharides, which are structural substances found in nature, such as chitin and cartilage.1

Glucosamine is classified as an amino sugar, meaning one of its hydroxyl groups has been replaced by an amino group (–NH₂). It is not found in an uncombined form but occurs in animals as part of glycolipids or polysaccharides. For example, it is a primary component of chitin, the structural polysaccharide in insect exoskeletons. Glucosamine is also found in some blood group substances.2
