Sugar Ring

The following reactions have been shown to occur during gas–liquid chromatography of carbohydrate derivatives: (a) deamidation, (b) change in size of the sugar ring, (c) rearrangement of acetal or ketal groups, (d) degradative rearrangement of acetylated amino sugars. The results emphasize that stability of a compound under conditions used in gas–liquid chromatography is a necessary prerequisite to the application of that technique; the precautions that should be followed to determine stability are indicated.

Carbohydrate Components

1. The sugars and amino sugars of hydrolysates of gastric secretion were determined by gas–liquid chromatography. 2. All the gastric aspirations examined showed on hydrolysis the presence of fucose, galactose, mannose, glucose, galactosamine, glucosamine, N-acetylneuraminic acid and sulphate. 3. Galactose and glucosamine were always found in equimolar amounts, but the galactose/galactosamine ratio in different aspirations was 2:1, 3:1, 4:1 or 5:1. Repeated gastric aspirations of each subject examined showed constant ratios of these carbohydrate components. 4. Fucose and sialic acid appear to be related to glucosamine and galactosamine respectively. 5. The carbohydrate components of extracts from the mucous glands of the body mucosa and antrum did not differ from those of gastric secretion.
