The Helical Structure of the Formula-1,3-Linked Xylan in Some Siphoneous Green Algae

Evidence of three distinct conformations

Evidence of three distinct conformations—single chain, single helix, and triple helix—of (1 → 3)-β-D-xylan in the solid and intact frond of green algae as studied by 13C-nmr spectroscopy

High-resolution solid-state 13C-nmr spectra of ( 1 + 3 ) -P-D-xylan from Bryopsis maxima and Caulerpa brachypus were recorded for various preparations from intact through dried frond to anhydrous and hydrated xylan, to gain insight into their secondary structures as compared with those of ( 1 + 3) -
