Galactogen

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... 

Molecular Structure of the Galactogen from Beef Lung, M. L. Wolfrom, Gordon Sutherland, and Max Schlamowitz,y. Amer. Chem. Soc., 74, 4883-4886 (1952). 

Galactose polysaccharides from animal sources include the galactogens of the albumin gland of the snail Helix pomatia), frog spawn, and beef lung (Chapter XII). The cerebrosides and gangliosides, occurring in con-... 

Three homozoopolysaccharides (glycogen, chitin, and lung galactogen) have been studied. The remaining heterozoopolysaccharides are composed of more than one type of sugar residue. The well-defined products are described individually below. Complexes of these with proteins are covered in a subsequent section. 

Polysaccharides are very widely distributed in the biosphere, being employed as a structural material (cellulose, xylan, chitin, etc.) and as a form for storing the monomers (starch, glycogen, inulin, galactogen, etc.).
