Id Subject Object Predicate Lexical cue
TextSentencer_T1 0-87 Sentence denotes The oxidation of some polysaccharides by the hydroxyl radical: an e.s.r. investigation.
TextSentencer_T2 88-94 Sentence denotes E.s.r.
TextSentencer_T3 95-435 Sentence denotes Experiments employing a flow system in conjunction with the TiIII-H2O2 couple show that dextrans react with the hydroxyl radical (HO.) via indiscriminate attack (except that abstraction of hydrogen atoms from carbons which are both linked by glycosidic bonds and included in the pyranose ring may be inhibited, possibly for steric reasons).
TextSentencer_T4 436-692 Sentence denotes Acid- and base-catalysed transformations of first-formed radicals have been demonstrated; the suggestion that such reactions can lead to glycosidic cleavage is supported by viscosity studies which confirm the pH-dependence of radical-initiated degradation.
TextSentencer_T5 693-881 Sentence denotes For galacturonan and related compounds, e.s.r. results indicate that reaction with HO. proceeds preferentially via abstraction of the hydrogen on the carbon adjacent to the carboxyl group.
TextSentencer_T6 882-986 Sentence denotes The crucial step in the subsequent degradation pathway probably involves a pH-independent rearrangement.
