Abstract:
:3-O-Methyl hexosamine was found for the first time and characterized as one of the sugar components of oyster glycolipid. The alditol acetate of this sugar was identified as 3-O-methyl-N-acetylgalactosaminitol acetate by comparing its retention time on gas chromatography and mass spectrum with those of the authentic sample synthesized in this laboratory. The new sugar, 3-O-methylgalactosamine, occupied the non-reducing terminal position of the carbohydrate moiety of the lipid and was linked to the penultimate hexose by a (1 leads to 3) bond.
