Fig. 2: Close proximities between moieties from three-fold screw xylan and amorphous cellulose were detected in sorghum secondary cell walls by CP-PDSD experiments with a short-mixing time (30 ms).
From: A grass-specific cellulose–xylan interaction dominates in sorghum secondary cell walls

Cross peaks indicate that the majority of intramolecular interactions and close intermolecular interactions between arabinosyl and xylosyl units from three-fold screw xylan and glucosyl units from amorphous cellulose were labeled in the spectrum.
