Solubility: easily soluble in water, soluble in hot methanol, slightly soluble in cold methanol and ethanol, insoluble in ether and chloroform.

It is a common amino sugar and a derivative of glucose. A compound formed by replacing the hydroxyl group on the second carbon atom of glucose molecule with ammonia chemicalbook group. A hydrogen atom on the amino group is often replaced by an acetyl group to form N-acetylglucosamine. It is rarely free in organisms and is mainly used as a component of chitin, glycoprotein and proteoglycan.

Glucosamine has the property of polyhydroxyamine and exists in the cell walls of crustaceans, insects, molds and bacteria in the form of polymers or derivatives. Chitin (the condensation polymer of N-acetylglucosamine) forms glucosamine when it is in water. α- The body is crystalline, melting point 88 ℃, and spins in aqueous solution[ α] D20100 ° → 47.5 ° (30 minutes). β- The needle like crystals were obtained from methanol, decomposed at 110 ℃ and rotated in aqueous solution[ α] D20247 ° (d2025.5 minutes).

Warm tip: in order to obtain the best use effect of the product, the material should always be kept at a low temperature under dry conditions to avoid frequent thawing and freezing. In order to ensure the stability of the product, please note that the package can only be opened after constant temperature drying!
