Additional doubts can be raised by the knowledge of the well-defined cellular steps in glucosamine formation and production of glycosaminoglycans such as chondroit...

متن کاملDetermination of glucosamine in raw materials and dietary supplements containing glucosamine sulfate and/or glucosamine hydrochloride by high-performance liquid chromatography with FMOC-Su derivatization: collaborative study.
A collaborative study was conducted for determination of glucosamine in raw materials and dietary supplements containing glucosamine sulfate and/or glucosamine hydrochloride by high-performance liquid chromatography (HPLC) with N-(9-fluorenyl-methoxycarbonyloxy) succinimide (FMOC-Su) derivatization. Thirteen blind materials, one pair of which were duplicates, were tested by 12 collaborating lab...

The National Institutes of Health-sponsored Gluc...
متن کاملGlucosamine Metabolism
Recent studies in this laboratory, concerned with hexosamine metabolism, required Gm-6-P,’ Galm-BP, and their respective N-acetyl derivatives. Several methods are available for the preparation of Cm-6-P, but there appears to be no previous report of Calm-6-P, although an acid-stable Galm-P has been isolated from cartilage (4). Earlier reports indicated that hexokinase and ATP would phosphorylat...
