Final proof of the structure of D-glucosamine as 2-amino -D-gluco-pyranose (I) was furnished as indicated below independently by both chemical14, 16 and x-ray methods.1 By the action of ammonia on 2,3-... [Pg.184]

Both methods of approach moreover proved that a series of methylated derivatives of D-glucosamine described by Cutler, Haworth and Peat,14 and most useful as reference compounds in this field, were all of the pyranose configuration. Further proof of the pyranose structure of methyl D-glucosaminide and methyl N-acetyl-D-glucosaminide was pro-... [Pg.185]

The phosphorylation of D-glucosamine (2-amino-2-deoxy-D-glucose) was first achieved by incubating it with brain extracts and ATP.266 Crystalline, yeast hexokinase plus ATP also phosphorylates D-glucosamine, to give the 6-phosphate, at a rate at least 75 % of that of phosphorylation of D-glucose ... [Pg.243]

Preparation of acetylated nitriles from oximes with pyridine-acetic anhydride. Penta-acelyl-n-glucosaminonitrile. One gram of D-glucosamine oxime hydrochloride was treated with 6 ml. of pyridine and 6 ml. of acetic anhydride and kept at 20° until solution had occurred. The solution was then concentrated and the crystalline residue was recrystallized from ethanol yield 1.8 g. (84%), m. p. 126°. [Pg.129]
