From: The preparation and characterization of a novel sphingan WL from marine Sphingomonas sp. WG

Structural characterization of WL-1.
(a) Sephacryl High Resolution (S-100) chromatogram of WL-1 fraction from partial acid hydrolysis of WL. (b)1H NMR spectrum (400 MHz) of WL-1 in D2O. The anomeric protons were labeled as A-E. (c) 13C NMR and DEPT spectra of WL-1 in D2O. Acetone-d6 was used as internal standard. (d) Proposed structure of the oligosaccharide WL-1. It should be pointed out that WL-1 also contained carboxyl groups and O-acyl groups.
