THE STRUCTURE OF AN ARABOGALACTAN FROM MONTEREY PINE (PINUS RADIATA)

Abstract
The two major components of the water-soluble polysaccharides from Monterey pine (Pinusradiata) are an arabogalactan and a glucomannan. The arabogalactan contained L-arabinose and D-galactose in the ratio 1 to 8. The polysaccharide is highly branched in structure and contains end groups of L-arabofuranose and of D-galactopyranose. Removal of the L-arabinose residues leaves a highly ramified galactan.
