seed mucilage galactoglucomannan has a backbone consisting of the repeating disaccharide [4)-β-Glc-(1,4)-β-Man-(1,], and most of the Man residues in the backbone are substituted by single α-1,6-Gal. CSLA2 is responsible for the synthesis of this patterned glucomannan backbone and MAGT1 catalyses the addition of α-Gal.

Galactoglucomannan oligosaccharides (GGMOs) are signalling molecules originating from plant cell walls influencing plant growth and defence reactions. The present study focused on their interaction with exogenous IAA (indole-3-acetic acid). GGMOs acted as auxin antagonists and diminished the effect of IAA on Arabidopsis primary root growth.

It has a backbone chain made up of d-glucopyr-anose and d-mannopyranose residues which are joined together by β(1 → 4)-linkages. Galactoglucomannan (GGM) is the main hemicellulose in Norway Spruce (Picea abies), the most common raw material used in the thermochemical mills in Scandinavia. It can be used isolated after an established procedure involving microfiltration [249]. Native galactoglucomannans (GGMs), which were isolated from thermomechanical pulping waters of Norway spruce, were modified through cationization, carboxymethylation, and imination at the reducing end with a primary long-chain hydrocarbon amine. The derivatives were tested for their papermaking properties. Galactoglucomannan (GGM) is the main hemicellulose class in wood of coniferous trees and could be potentially utilized as a possible health-promoting substance for food and pharmaceutical industry.

ABSTRACT: A galactoglucomannan oligosaccha-ride (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs. The GGMO substrate contained increased concentrations of oligosaccharides containing mannose, xylose, and glu-cose, with the mannose component accounting for 35% of DM. A galactoglucomannan oligosaccharide (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs. The GGMO substrate contained increased concentrations of oligosaccharides containing mannose, xylose, and glucose, with the mannose component accounting for 35% of DM. O-Acetyl-galactoglucomannan (AcGGM) is the major soft-wood hemicellulose. Structurally modified AcGGM and hydrogels of AcGGM were prepared. The degree of substitution (DS) of AcGGM was modified enzymatically with α-galactosidase, and chemically with an acrylate derivative, 2-hydroxyethylmethacrylate (HEMA).

Hemicellulose in Softwood - galactoglucomannan There is a galactose richer fraction of galactoglucomannan with a galactose to glucose to mannose ratio of approximately 1 : 1 : 3. Galactoglucomannan are easily depolymerized by acids and especially so the bond between galactose and main chain.

Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener.
