Lysodektose - A New Trisaccharide from Micrococcus Lysodeikticus which is Transformed into an Aminoxyl Free Radical with the Loss of an Electron

Abstract

A new trisaccharide 6-0-(2-deoxy-2-/N-methyl/-hydroxylamino-β-D-glucopyranosyl)- α,α-trehalose named lysodektose has been isolated from Micrococcus lysodeikticus. In oxygenated solutions or in the presence of K₃ Fe (CN)₆ lysodektose is transformed into a long lived free radical. Spin trapping data are presented and functions are suggested for the substance.

Key Words:

• lysodektose
