Abstract
L-Galactose was identified in a hydroly-sate by paper partition chromatography and as the methyl-phenylhydrazone. The m.p. was low, due to the presence of a small amt. of D-galactose. There was one reducing group in the polysaccharide per 150 galactose residues. Periodate oxidation gave a consumption of one O per 60 residues. A structure with the galactopyranose residues linked through the 1 and 3 positions and carrying the sulfate group on C4 is in agreement with the analytical results.
