Starting-materials for Preparing Monomethyl Derivatives

This sugar has not so far been synthesized. A monomethyl-D-galactose, isolated from the hydrolysis products of methylated damson gum, is considered by Hirst and Jones,28 on good evidence, to be the 

As an aid to workers who may have need to identify a monomethyl-galactose there are recorded in Table I appropriate data and references.

This sugar has not been prepared synthetically. It is, however, a frequent constituent of the hydrolysis products of methylated polysaccharides containing galactose radicals, for example plant gums26 and the so-called galactogen of the albumin glands of the snail Helix pomatia.27,28
