The reaction of carbohydrases with phenolic glucosides

Abstract
The incubation of almond emulsin, or enzyme preparations from broad bean, with arbutin produces p-hydroxyphenyl B-gentiobioside. A transglucosy-lation reaction catalysed by B-blucosidase is involved with arbutin molecules serving as both donors and acceptors of D-glucopyranosyl residues. Salicin is partially converted into o-hydroxybenzyl B-glu-copyranoside by the almond and broad-bean preparations.
