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-... 

It was found possible to saponify ovomucoid with sodium hydroxide and to methylate simultaneously with methyl Bulfate, the carbohydrate residue thereby forming an N-acetyl methyl derivative.14 Hydrolysis of this material yielded N-acetyl-3,4,6-trimethyl-D-glucosamine (7 moles) (LIVJ, D-mannopyranose (2 moles) (LV), 3,4,6-trimethyl-D-mannopy-ranose (1 mole) (LVI), and tetramethyl-D-galactopyranose (1 mole) (LVII).
