Hi, I have extracted glucosamine from lobsters shell, however my extracts are not soluble in water,Could you please tell me why and give me a suitable way to dissolve them in water?
Chemically, glucosamine is 2-amino-2-deoxy-alpha-D-glucose. It is a
crystalline colourless and odourless substance with sweet taste. Glucosamine is readily soluble in water with a log P of -2.2 and practically insoluble in ethanol (96%). It has a pKa value of 6.91 at 37°C. When heated above 80oC, it undergoes Maillard reaction and its colour gets faded.
