Abstract

Arabinoxylans are important components of the cell walls of grass and legume forage plants. The (1-. 4)-/9-~-xylopyranan backbone of these polymers carries occasional aL- arabinofuranosyl branches at the 2-and 3-positions of the Pxylose units. 2 Some of the aL- arabinofuranosyl units are also esterified, through the 5-position, to p-coumaric and ferulic acids? These hydroxycinnamic acids may in turn be etherified to lignin, providing a cross- ...
