CCVIII. Oligosaccharides Separated after Acetolysis of the Group Mucopolysaccharide from Pig Gastric Mucus Third Report: “Gastro-N-disaccharide”

Abstract

1. A disaccharide “gastro-N-disaccharide” was isolated as a deacetylated acetolysis product of the group mucopolysaccharide from pig stomach mucus.
2. Its physical and chemical properties were examined.
3. It has been established to have the structure of galactose-4-α-N-acetylgalactosaminide by analysis, oxidation experiments with hypoiodite and periodate, Osaki-Turumi (Morgan-Elson) test and examination of its infrared spectral absorption.
