Structural elucidation of a neutral fucogalactan from the mycelium of Coprinus comatus.
A water-soluble fucogalactan (CMP3), with a molecular mass of 1.03 x 10(4) Da as determined by high-performance size-exclusion chromatography (HPSEC), was obtained from the crude intracellular polysaccharide of Coprinus comatus mycelium. Its chemical structure was characterized by sugar and methylation analysis along with 1H and 13C NMR spectroscopy, including NOESY and HMBC experiments for linkage and sequence analysis. The polysaccharide is composed of a pentasaccharide repeating unit with the following structure: [structure:see text].
