XIX. Polyhydroxylic Acceptors for the . ? -Glucosidase of Staohybotrys Atra

Abstract

Transfer to polyols appears to take place principally to the terminal primary hydroxyl group. Transfer to the penultimate secondary hydroxyl group in any amount was only demonstrated for the pentitols, adonitol, and L-arabitol. Where the concentrations of the acceptor and the initial transfer product are of the same order of magnitude, there is measurable transfer to the initial transfer product to give molecules containing two glucosyl residues. Where all hydroxyls are secondary, as in myoinositol, no one transfer product predominates.
