Rye Water-Soluble Arabinoxylans Also Vary in Their 2-Monosubstituted Xylose Content

Rye (Secale cereale L.) is rich in total and water-soluble arabinoxylans. Recently, a large variability in the structure of the water-soluble arabinoxylans from rye was described (Bengtsson and Aman 1990, Bengtsson et al 1992a, Vinkx et al 1993). In the article by Vinkx et al (1993), structural information was mainly gained by H-1-nuclear magnetic resonance (NMR) and C-13-NMR spectroscopy using peak assignments reported for wheat (Hoffmann et al 1992) and rye arabinoxylans (Bengtsson and Aman 1990). This article provides additional information obtained by methylation analysis.
