“…The O-acetyl-4-O-methyly glucuronoxylans present in hardwoods are substituted by 4-O-methyl glucuronic acid (MeGlcA) and acetyl groups at a ratio of 1:7:10 to xylose (Magaton, Colodette, Pilo-Veloso, & Gomide, 2011;Spiridon & Popa, 2008;Teleman, Tenkanen, Jacobs, & Dahlman, 2002). The predominant hemicellulose in grasses is arabinoglucuronoxylan, which is substituted with arabinose side chains at a ratio of 1.3:2:10 to MeGlcA and xylose (Evtuguin, Tomas, Silva, & Neto, 2003;Izydorczyk & Dexter, 2008;Westbye, Köhnke, Glasser, & Gatenholm, 2007).…”
