It is probable that the arabinose residues, along with the glucose and galactose residues, are derived from substituted galactans. Timell (6) reported that tension wood, the wood formed when hardwood is subject to an outside influence, such as physical pressure, was high in glucose substituted galactan. Similarly, Meier (7), in studies on the hardwood European beech, found that it contained tension wood, the H/C of which was predominantly glucose and arabinose substituted galactan.
