Mannoglucuronoglycans from plant sources (original) (raw)

Food Hydrocolloids, 1991

Abstract

Abstract A comparison is made between the molecular structures of three polysaccharides of plant origin, all of which contain alternating sequences of D -glucuronic acid and D -mannose. They vary considerably in the degree of substitution of OH groups in the core structure, O-3 of both the uronic acid and the neutral sugar being favoured. FAB-mass spectrometry showed the presence of (GlcA-Man)9 in a hydrolysis product of the least-substituted polysaccharide.
