Abstract
Galactogen, prepared from Helix pomatia, was hydrolyzed with 0.1 N sulphuric acid, and the products of the reaction separated by paper chromatography. This galactogen has been shown to consist of 7 parts D-galactose to 1 part of L-galactose. It was found that L-galactose was liberated preferentially; thus in the 1st 3 hours almost 2/3 of the total L-galactose, but only 1/6 of the D-galactose was liberated. The total hydrolysate, the monosaccharides D- and L-galactose and the cleavage products present at any given time all show identical specific rotations.Keywords
