UV-method for the determination of D-Glucosamine,
D-Glucosamine sulphate and N-Acetyl Glucosamine in food
supplements, foodstuffs, beverages and other materials

(1) Glucosamine sulphate → D-glucosamine + sulphate

(2) N-Acetyl Glucosamine → D-glucosamine + acetate

(3) D-Glucosamine + ATP → D-glucosamine-6-P + ATP

                   (glucosamine 6-phosphate deaminase)
(4) D-Glucosamine-6-P + H2O → D-fructose-6-P + NH4+

    (phosphoglucose isomerase)
(5)  F-6-P             →            G-6-P

     (glucose-6-phosphate dehydrogenase)
(6) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+
