Isolation and Identification of a Choline-linked Mannobiose in the Glycoproteins of Fusarium sp. M7-1

Abstract

An unidentified oligosaccharide was isolated from an oligomer mixture derived by alkaline borohydride treatment from glycopro-teins of Fusarium sp. M7-1. The isolated compound was identified as O-α-D-Mannopyranosyl (1→2)-D-Mannitol-6-phosphocholine by NMR and Ms spectrometry.
