Description
Fenton Oxidation of Laminaran Carbohydrate. B1,3 glucan (laminaran), a major fungal wall polysaccharide, was oxidized using a molar ratio of monomer/Fe+2/H2O2 of 10:1:1 (primarily). We labeled the reaction products and profiled them as fluorescent-labelled molecules in polyacrylamide gels and as hydrophobic-tagged molecules using reverse phase liquid chromatography/mass spectrometry (HPLC/MS). Sub-stoichiometric concentrations of Fe+2 and H2O2 fragmented laminaran into smaller molecules containing carbonyl and carboxylic acid groups visible on fluorescent-labelled carbohydrate polyacrylamide gel electrophoresis. HPLC/MS analysis of glucan fragments showed masses consistent with six classes of molecules: aldoses, dialdoses, uronic acids, hexosuloses, aldonic acids, and hexulosonic acids.
