Research on the chemical structure and physiological activity of galactan and galactan-containing polysaccharides of higher plants is reviewed. The principal chain in galactan-containing polysaccharides consists of 1–3, 1–4, 1–6, and α- and β-bonded D-galactopyranoses. The side chains contain separate or bonded chains of galactose, arabinose, glucose, rhamnose, and uronic acids. The relationship of chemical structure and physiological activity of the polysaccharides of higher plants is discussed.
