Research Abstract

A carbohydrate model compound, methyl β-D-glucopyranoside (MGP), isomers of MGP with the stereo configuration of a hydroxyl carbon different from MGP, and deuterated MGP’s with a deuterium substituting the hydrogen of MGP bonding to a hydroxyl carbon were treated together with a phenolic compound as the generator of active oxygen species (AOS) under oxygen bleaching conditions. It was indicated that the stereo configuration influences the reaction of model compounds with AOS and AOS certainly abstract the hydrogens of MGP bonding to hydroxyl carbons.
